Long, near100acre of water in the greenhouse is full of life。As much as collected by the stormwater project1000A cubic pool of rainwater，Flowing slowly and meandering through it，The more it flows, the clearer it becomes，The cycle continues。This is the reporter in Longquan Wu Village, Longquan Town, Mentougou District today“Longquan Ecological Park”.

10,000 cubic meters
。This is based on the ecological purification of the Yongding River water system、Research topic targeting the restoration of aquatic animals and plants，It is a project jointly developed by Beijing Agricultural College and Longquan Wucun，What we see so far is only the first phase of the project。The project includes comprehensive utilization of rainwater and floodwaters，Study on screening of self-purification ecological cycle chain of aquatic animals and plants in Yongding River，Mountain wild vegetables、Research on Fragrant White Apricot Seedling Breeding Center and Aquatic Animal and Plant Food Processing Safety Standard System。

“In the past, most rainwater and flood collection tanks were built halfway up the mountain，Our rainwater collection tank is built on the lowest flat land，This is done to maximize the collection of rain and floods in large areas、The problem of comprehensive utilization。”“Longquan Ecological Park”Introduced bet365 online casinoby Engineer Deng Deming in charge of infrastructure，Putting this project into use，It not only promotes the research on the ecological cycle of the Yongding River system，We also solved the problem of biological purification and irrigation of rainwater and floods in hundreds of acres of land in the front of the park。
As far as we know,Currently conducting screening research on the self-purification ecological cycle chain of aquatic animals and plants in the Yongding River，Mainly here100In greenhouses with many acres, through qualitative, positioning and quantitative delivery40species60varieties of aquatic animals and plants，Simulating the ecological environment of the Yongding River system，Integrate the terrestrial plant system and aquatic animal and plant system on both sides of the river，Impact on the self-purification function of river water，Conduct screening adaptability research，In order to start from the protection of the Yongding River ecosystem，Improving soil and water in mountainous areas、Rational development of aquatic life、Terrestrial resources、Provide a model to ensure ecological security，For those living in the Yongding River Basin in modern times，such as fish、River crab、Dozens of extinct and endangered animals and plants including blue shrimp，Conduct population recovery and conservation research，Provide relevant basic research data and feasibility analysis for the construction of ecological barrier in western Beijing、Reference results。
Rain and flood water are retained as crops in mountainous areas“Quench your thirst”
There are many rocks in Taihang Mountain、Thin soil layer、The difficulty of storing water is obvious to all。Mentougou is located at the eastern foot of the Taihang Mountains，It is the only pure mountainous area in Beijing，The rains and floods in spring, summer and autumn every year often become“Passenger”. In order to let“Passenger”Leave it for the crops“Quench your thirst”，Mentougou District utilizes the natural precipitation of mountains to collect water，Constructed a large number of rainwater and flood comprehensive utilization projects，Effectively alleviates the problems of mountainous agriculture“Thirsty”Status. Based on this“Research on the biological purification bet365 online casinowater circulation system of Longquan Ecological Park”It is an effective means of ecological self-circulation purification of the Yongding River water system.
Tan Jie, director of the district’s agricultural committee, told reporters，The tourism agriculture in Mentougou District has developed rapidly in the past two years，The scale of the agricultural tourism park increases to every year10The speed of increasing。Each park is based on the principle of effectively utilizing the park’s rainwater and flood collection and filtration systems as an important supplement for irrigation water，On the premise of making full use of the adaptability of improved native plants to their own ecological environment，Carry out structural adjustment，Achieve scale development。
As far as we know,“Fifteen”During this period, the area will integrate farmland water conservancy infrastructure，Special funds invested in total7300More than 10,000 yuan, new ponds, reservoirs, and water cellars105, laying water pipeline100More than 10,000 meters, annual increase in water storage capacity24010,000 cubic meters, improved water conservation and controlled irrigation area610,000 acres, land consolidation1.4Ten thousand acres. The annual water storage capacity that has been built before is up to30010,000 cubic meters859chutangba、Reservoir、Comprehensive stormwater utilization facilities such as water cellars still play an important role。
Next year，This area will continue to increase the hillsides、River、Pengtang、Construction of comprehensive rain and flood utilization facilities in villages，Add58210,000 square meters of water collection area, annual increase in water storage capacity59Ten thousand cubic meters.
Ecological industry has become the locomotive of Mentougou agriculture
Mentougou District is an ecological conservation development area in Beijing，Strengthen ecological protection and construction，Developing ecological industries is the functional positioning requirement of Mentougou District。This year5month26日，Vice Mayor Niu Youcheng during an inspection in Mentougou，Fully affirmed the district’s approach of combining ecological research with bet365 online sports betting mobilerural industrial development。
Currently, the whole area8.6Ten thousand acres of irrigated forest and fruit fields7.9Ten thousand acres through the hillside、River、Pengtang、Village rainwater and flood comprehensive utilization project realizes water-saving irrigation。Direct electricity saving every year430Wandu, cost saving220More than ten thousand yuan.
As Beijing Ecological Restoration Science and Technology Experimental Zone，Mentougou District aims to create a national ecological zone，Actively implement the ecological district strategy。“Fifteen”During the period, it will be used for investment in ecological agriculture projects7Billion yuan, yes“Ninth Five-Year Plan”Period3times；Completed the control of sandstorm sources in Beijing and Tianjin in five years、Comprehensive agricultural development and ecological management such as soil and water conservation580square kilometers，Passing the implementation of the first phase of the comprehensive management project of the Mentougou section of the Yongding River，Protected water source and wetland。
“Eleventh Five-Year Plan”Period，This district will also be in rural areas，Adopt water that complies with the "Urban Recycled Water Utilization" standardsCWTCraft, Construction189Small sewage treatment facility，All treated sewage will be used for household toilet flushing、Water-saving irrigation、Landscape water reuse, etc.。Also，A pond and dam will be built6Block, reservoir135seat, water storage capacity is sufficient1.4Water-saving irrigation of thousands of acres of land.
