One of the four major flood control rivers in China
Yongding RiverIt is one of the four major flood control rivers in ChinaHaihe River SystemThe largest river with a total drainage area of 47000 square kilometers. The drainage area in Beijing is about 3200 square kilometers. The Beijing section of the Yongding River is 170 kilometers long, divided intoGuanting GorgeSection, plain urban section, plain rural sectionMentougou、Shijingshan、Fengtai、FangshanandDaxingFive districts.Yongding River is also the mother river of Beijing, giving birth to Beijing's profound cultural heritage and unique human resources
Yongding River is faced with problems such as water volume reduction, water quality deterioration, river ecological environment deterioration, and destruction of flood control dams in the basin.Since the 1970s, Beijing has neglected the ecological conservation andUrban landscapeAs a result, the ecological environment along the Yongding River and its banks has gradually deteriorated, seriously affecting its image as the "mother river" of Beijing.
As an ecological link connecting the southwest region and an important ecological corridor in Beijing, the development and management of the Yongding River can not only greatly improve the ecological environment in the southwest region of Beijing, enhance the regional economic value, but also implement the overall urban planning of Beijingurban ecology Environmental quality, accelerating Beijing's international constructionlivable city And other aspects play an important role.
The "four lakes and one line" project started in 2010 has built a green ecological corridor with water linking the landscape and water green. At the end of 2010, the first stage will be in Mencheng Lake, Lianshi LakeWanping Lake150 hectares of water surface will be formed and 120 hectares will be afforested.Completely eliminate sand and dust, build a good ecological water environment, demonstrate and drive the ecological management of the whole Yongding River, and develop the Yongding RiverWaterfront economyCreate conditions.

Lianshi Lake
Lianshi Lake is located at the junction of Shijingshan, Mentougou and the west of Fengtai River in Beijing. It was built on the beach of the original Yongding River.This is a section of the Yongding River. Because the Yongding River has dried up in the past 30 years, it has become a dry riverbed.
Lianshi Lake
The construction of Lianshi Lake Wetland Park was started in August 2008 and completed in October 2011, with an investment of 467 million yuan.A landscape corridor of vastness, freshness, freshness and flexibility has been built on the original concave riverbed.The total area of the park is 226 hectares, including 102 hectares of water surface, 110 hectares of green area and 14 hectares of supporting infrastructure.There are one main scenic spot and eight scenic spots. The main scenic spot mainly inherits the water diversion culture, flood control culture and water control culture of Yongding River through four elements of "mountain, water, lotus and stone".Design concept: bring green with water, support water with green, store plenty of water, and keep green with less water.
Landscape theme: The spirit of Zhong Lingxiu, the beauty of all things.
