The water surface area of Xuantian Lake is more than 20 square kilometers. This lake looks like a large octopus from the air, with a large belly and many antennae. The belly of the octopus is the waters near the Diaoyutai and the Xuantian Sea. The tentacles of the octopus are those waterways, rivers, streams that penetrate deep into dozens of valleys.

It rains a lot in the south. Annual rainfall reaches more than 1000 mm. It is normal to say that it rains twice in three days. Especially in the summer, there are many typhoons, and there are afternoon rainstorms at more than 2 p.m. every day. It is a precipitation phenomenon caused by convective movements in the atmosphere, and is also customarily called a hot thunderstorm. It is one of the four major forms of precipitation in the world (convective rain, topographic rain, frontal rain, typhoon rain), and often occurs in the summer afternoon of tropical, subtropical or temperate zones, with the most common in tropical and subtropical regions. Due to the strong sunlight and strong evaporation, the air expands and rises by heating, cools at high altitudes, and condenses into rain. Although the rainfall is short, the heavy rain is pouring, and it is often flooded due to insufficient drainage.

The area of the Xishan Restricted Area has reached more than 600 square kilometers. Red Star Farm uses less than 30 square kilometers of plains in the northeastern part of Xishan for farm land, and the Sword Base covers an area of 10 square kilometers. Together with the Air Force Special Service Regiment and the Armed Police Brigade, the armored regiment covers an area of only a few square kilometers. Others are forest stars with pristine vegetation, dotted with lakes, rivers, and pools.

Therefore, if there is no perfect drainage system in the restricted area. It is very easy to cause waterlogging, flash floods. The drainage system of the entire exclusion zone, ditches, rivers, ponds are artificially arranged. All the water eventually flows into Xuantian Lake. This is called the fact that the fertilizer water does not flow into the fields of outsiders. In Feng Shui, it is said that the eight directions come to the court.

There are two piers at Xuantian Lake. A sightseeing marina right here in Diaoyutai. There are two painting boats, one large and one small. Richly decorated cruise. Boat means boat, and is often used to refer to a boat in general, and a painted boat is a gorgeously decorated boat, which is generally used to play on the water, to enjoy the scenery in the water and on both sides, and sometimes to feast and drink. The large one can accommodate hundreds of people, and it is a two-story antique wooden building. The smaller one also has more than 30 seats. In addition to this, there are 3 speedboats. There is one for 12 people. There are 2 4-seater ships.

Another wharf is the mouth of the Xuantian River at the north of Xuantian Lake. This pier is a dual-use dock. It is the docking place for the boats used by the Red Star Farm for surface operations, and it is also the venue for the water training subjects of the Sword Base.

At this time, Xiang Ming stood on the bow of the largest painting boat to blow the wind. This is the program after lunch - a lake cruise.

Xiang Ming and his classmates were in the largest boat. Old man, they're in the small one. Don't look at the old men who often go into the lake to play. Xuantian Lake is very beautiful and magical, never get tired of seeing, mainly because there are many cliffs, many towering ancient trees, and the strange-shaped vines hanging down the water surface on those stone walls are very beautiful. Flocks of egrets perched on the treetops, red-crowned cranes foraging in the shallow waters on the shore, wild ducks frolicking in the grass, swans wandering on the water, and occasionally mandarin ducks playing in the water, and flocks of monkeys on the island in the middle of the lake surrounded by water。。。。。。 I saw that the surrounding water was surrounded by mountains. In the distance, the mountains are undulating and undulating. The water of the lake is crystal clear. The surface of the lake is sparkling, the breeze is gentle, and from time to time there are layers of waves. Surrounded by mountains, the blue waves ripple. It has the artistic conception of Qiandao Lake, that kind of beautiful scenery. In particular, it enters a narrow waterway with exposed stone walls on both sides. (The water level drops during the dry season) and there are many carvings in these stone walls. Needless to say, this is the Taoist priest of Xuantian Temple, as well as the literati and dignitaries who came to Xuantian Temple to play, and the princes and emperors will want to linger for hundreds of generations to leave stone carvings. There are stone carvings of landscape figures, as well as stone carvings of ancient poems. It's just a piece of precious historical artifact. Thousands of years of civilization are recorded. It's very ornamental and research-oriented. These are still under the surface. There are also many carvings in the stone walls on those waterlines. The main reason is that the ancients did not expect that the water level of the lake here would rise due to the construction of the reservoir. A lot of stone carvings were drowned. Many of the stone walls are overall carved figures, which needless to say have a fight with the stone walls of the Mogao Grottoes in Dunhuang. There are many stone walls and caves here, of course, the carved figures in them cannot be Buddha's feet, most of the stone carvings here are Taoist figures, as well as many mythological figures. The tallest stone carving is a Taoist priest. Here you can see the stone carvings of the four masters and apprentices of Tang Hate riding a white dragon horse to the west to learn scriptures. You can also see the carving of the story of Jiang Ziya's fishing wisher taking the bait, and the stone carving of the story of Confucius telling the story of a hundred sons listening. And so on, hundreds of stone carvings. These stone carvings deeply attract the old chiefs of the old people's residence, who often go into the lake to watch and relax.

"Xiang Ming is so beautiful here. Li Qian sighed beside her, the lake scenery is so beautiful that it can't be expressed in words. This is just leaving the Diaoyutai pier and entering the middle of the lake, heading towards the mountains to the south.

"Hehe, Li Qian, this is just the beginning, the next itinerary is more exciting, you just ask my sister, hehe, let her be your tour guide and introduce you to it." Anyway, I think that my home is better than there, and I have been here, and I rarely go to the scenic spots in China to play, where there are too many traces of man-made. This is pure and natural, that ancient poem doesn't say, Guilin's landscape is the best in the world, Yangshuo's landscape is Guilin, in fact, I want to add a sentence. As soon as the Xuantian view of the landscape came out, the beautiful scenery of the world was eclipsed. Xuantian view of mountains and rivers in Yangshuo. Li Qian: You see that there are many peaks on both sides of the lake, which are stone mountains, is it very Guilin-like? The stones are strange, the mountains are green, the water is beautiful, the caves are strange, and the stones are beautiful. Thousands of rocks and ravines, strange peaks and caves. Originally, we are not far from Guilin, and the peaks here are also the Kester landform, which also belongs to the remnants of the Guilin plate. The eastern foothills of Guilin's Dayao Mountain. Anyway, it's the intersection of several mountain ranges. To the north is the Koster landscape (separate stone hills), to the south is hilly terrain and to the east is a small plain. To the west is the mountains. Hehe, let my sister be the narrator, she is an idle person, hehe province I took the trouble to introduce you to you alone. ”

"Hehe, you're just trying to be lazy. But I'll go find your sister. ”

"Li Qian, I'm not lazy. I'm very busy, you'll know what I'm busy with in a moment haha. ”

"Ignore you. ”

"Li Qian, give you a little speaker, you bring it to my sister. ”

"Okay, I'll bring it to her for you. Li Qian took the portable loudspeaker that Xiang Ming took out and turned around and entered the cabin.

Xiang Ming watched Li Qian enter the cabin and smiled.

Eyes turn to the sides of the boat. In the waves of the painting boat, I faintly saw more than 30 white figures in the water. They chased the two boats. One moment on the left, one on the right, and the other on the front. They frolic and chase in the water, sometimes jumping out of the water and sometimes making a trick dive. In fact, their appearance has long been discovered by some sharp-eyed students. No, everyone flocked to both sides of the boat to look into the water. These white figures are the freshwater species bred in captivity by Xuantianguan, and they are also national first-class protected animals - the baiji dolphin, which is listed among the 12 extinct species. Whitetip whales, white-tipped, white-fledged, white-clipped, blue-finned, Jiangma, Chinese finless porpoise, Yangtze finless porpoise and Yangtze river puffer fish are endemic freshwater cetaceans in China, which are only found in the middle and lower reaches of the Yangtze River. In the 80s of the 20th century, due to various reasons, the population of white-sided dolphins plummeted, and in 2002 it was estimated that there were less than 50 individuals, and they were known as "giant pandas in the water". The white-sided dolphin is a family of its own, listed as a national first-class wild protected animal, and one of the 12 most endangered animals in the world. On August 8, 2007, a report was published in the journal "Royal Society Bioletterhead", officially announcing the functional extinction of the white-sided dolphin. However, in Xuantian Lake, you can see groups of baiji dolphins, which is not exciting.
