Out of Lingquan Cave, walk up the stone steps more than 100 meters, and you will arrive at Xixi Mountain Villa. "Xixi Mountain Villa" is carefully designed to make visitors feel the coolness of the cool breeze in summer and the warmth of the warm wind in winter. It was built on the mountain layout in Qingfeng Cave to draw the breeze out of the cave. This is a successful tourist cave building. According to local records, the mouth of the cave is "hot summer, the wind comes out of the mouth, and the cold is irresistible"; In the middle of winter, the hole is like a "spring breeze, warm and warm". The reason is that there is a 90-meter-high cave at the entrance of the cave, and the space is also large. When the temperature difference between inside and outside the cave is large, air convection is formed. In summer, the cold air in the cave flows out from the lower hole, and in winter, the ground temperature is low, and the cold air sinks from the upper hole, forcing the warm air in the cave to flow out from the lower hole, thus making the wind blown out of the Qingfeng Cave warm in winter and cool in summer. This wind speed caused by convection can sometimes reach 2 ~ 3m/s, hence the name "Green Wind Tunnel". The whole cave covers an area of more than 2,700 square meters, and there are 36 scenic spots, among which "Hanging Lotus Cloister", "Thousand Foot Palm", "Three Mountains and Five Mountains", "Witch Mountain Goddess", "Fifty-three Ginseng" and "Birds Returning to their Nest" are the best, attracting tourists to stop for a long time.
Aiyun Cave is 800 meters away from Qingfeng Cave, and you have to climb Tiemao Mountain to get to the entrance. It is famous for its strangeness. According to local records, Jinyun Cave, also known as Yun Qi Cave, is named after the phenomenon of "it rains when it rains" at the entrance. It is said that when it rains tomorrow, there will be clouds coming out of the mouth of Jinyun cave, which is more than ten meters higher than the mouth of the cave and suspended in the cloud column. Seen from a distance, the scenery is charming. In the early morning of winter and spring, under the illumination of the morning light, there are also clouds around the hole. Because when it is going to rain, the pressure of the ground atmosphere will decrease, which has little effect on the hole, so the high-density air containing water vapor rushes to the hole in the shape of a cloud column; On a sunny morning in winter and spring, the morning sun has just come out, and the air on the ground is relatively cold and dense, while the air in the cave is relatively warm and dense. The cold air on the ground sinks into the cave, forcing the light and wet air in the cave to rise to the mouth of the cave and meet the low-temperature air outside the cave. The wet and warm air condenses into fog and floats across the hole like a cloud, forming a spectacle. Aiyun Cave has been opened for sightseeing, covering an area of more than 6,000 square meters, and the sightseeing distance can reach 360 meters. Daxiong Hall is the tallest of the three caves. The landscape is rich and colorful, among which "welcome screen", "hanging curtain of the sky", "Dragon Palace under the sea", "Dinghai Shenzhen", "bells and drums chime", "gold and silver double sunflower" and "double love stone pillar" are the most vivid and moving. In the "fairyland outside the sky", sparkling stalactites, continuous sky, peaks and valleys, and clear springs gurgling; On the "stone chime", the chime hummed, and the sound echoed around the beam, adding a mysterious and ethereal feeling; In the "Guanghan Palace", which is silvery, secluded and deep, and the balcony is looming, you can vaguely see the Tiangong Que where Chang 'e dances, WU GANG cuts laurel and Jade Rabbit makes an alchemy. In Jinyun Cave, it is 1 m in diameter, with large petals of apricot blossom color and silvery white, as big as a cattail leaf fan, and petals with pleated skirts. There are crystal dew on it, and there are many sunflower seeds inside, which are lifelike and beautiful. "Dinghai Shenzhen" is actually a slender stone pillar with a diameter of less than 10 cm and a height of 7 meters. It has a dome at the top and a floor at the bottom. It is slender, straight and indomitable, which makes the viewer amazed. The formation of this natural stone pillar is supersaturated calcium carbonate water, which seeps from the cracks at the top of the cave. Due to the change of environment, calcium carbonate is produced at the top and bottom of the cave at the same time, which grows with each other. Over time, the two are interrelated.
According to the research, Lingqi Cave is located in Shiping syncline area of the west Zhejiang fold belt. In the long geological history, it is in the shallow sea environment of northwest Zhejiang depression. From 300 million years ago to 280 million years ago, carbonaceous rocks of Huanglong Formation and Chuanshan Formation of Upper Carboniferous in Upper Paleozoic were deposited. The stratum is thick and the limestone is pure. Coupled with the action of many crustal movements in the later period, many faults, joints and cracks were formed in limestone. Surface precipitation goes deep into the ground along these cracks, and they meet each other to form underground rivers, dissolve limestone and produce huge potholes. Leave the cave on the surface of the underground river, accept the precipitation of water containing calcium carbonate oozing from the surface, generate peculiar calcium carbonate body, and form an "underground art palace".
1980 Lingqi Cave was renovated and opened. There are unique service facilities in the cave area, such as Xixi Mountain Villa, Xiang Yan Village, Cuigu Mountain Residence and Xialou Restaurant. Near the cave, there are grotesque and abrupt stone buds everywhere-Lingqi Stone Scene; There is the famous Yanshan tea-Eagle Rock Cloud Tea; Shou Chang also has famous specialty kumquat cake and white lotus.
While wandering in the cave, you must not forget Baisha City and Meicheng. Baisha City is located in the downstream of Xin 'anjiang Power Station, and the river passes around the city. The annual temperature is around 14℃, making it a famous summer resort, tourist and rest city. Meicheng, an ancient town, is known as "the hometown of mountains and rivers" and "the unique county". This is where people gather. There are scouts in Tonglu, the hometown of the Yellow Emperor, and Diaoyutai, a hermit in the Eastern Han Dynasty, which is famous all over the world. If you flow eastward along Fuchun River, you can enjoy the beautiful scenery of Fuchun River, such as "clean wind and smoke, Tianshan Mountain * * *" and "strange mountains and different waters, chinese odyssey".
