"people say that we rely on the mountains to eat the mountains, but in the end, we rely on the sea to eat the wind and flying sand." Wu Jinchang, the head of the woods in Guanyin District, Taoyuan, said with a wry smile. The forest is located on the northwest coast of Taoyuan. Of the total area of 680 hectares, 400 to 500 hectares belong to the Guanyin Industrial Zone, leaving only a little agricultural land and housing.

However, today's scene is not what it used to be in the woods. In the Guanyin district, which used to grow large areas of rice and watermelons, in the early years, sulfur dioxide emissions from Linkou thermal power plant affected farming, and because of the policy, residents living in the Amping area of Shimen Reservoir were relocated, and large areas of coastal windbreak forests in the woods were removed for residential use. Strong sea breezes also make it difficult for crops to grow.

In the trend of industrialization, the agricultural landscape is gradually transformed into cement buildings, young people leave home to work, and the fallow farmland has become a wasteland overgrown with weeds, followed by red fire ants and wild rats.

In the face of the environmental problems caused by fallow farmland and the needs of local industrial transformation, after manpower training in rural regeneration programs and understanding of household simple environmental facilities such as "symbiosis of fish and vegetables" and "rain" in low-carbon neighborhood programs, the chief and community partners had an idea: "Why don't we just use this land to make a huge version of symbiosis of fish and vegetables plus rain?"

So in 106, the community used 70,000 yuan in planned funds to build the first demonstration ecological flood detention basin. The location is located next to the area where the community waterway converges and used to be most easily flooded, and the waste farmland is dug deep, the earth embankment is widened and the soil embankment is widened and heightened, and water pipes are buried to become a huge pool where ── can store water in case of drought, lotus flowers can be planted in the pond for viewing, and Wushu or Jinli are stocked to solve the problem of longevity snails. In case of heavy rain, the water level of the pool should be lowered in advance to take over Rain Water, which can effectively slow down the flooding caused by heavy rainfall for a short time.

Since it does not need to spend a large amount of project money, it can achieve the effect of reusing idle land and reducing the problem of flooding, and planting lotus does not require much manpower, and it is more cost-effective than receiving subsidies for fallow farming of agricultural land. as a result, more and more landlords are willing to provide land as ecological flood detention ponds. At present, the total area of the detention basin in the community has reached 8.8 hectares, and the maximum water storage capacity can reach 79200 cubic meters.

The flood control measures built by the community can operate smoothly, but they can only be completed with the efforts of all. The community energy accumulated in the woods for more than a decade, since the establishment of the "Community Watch team", there have been more than 200 volunteer teams serving community elders and environmental protection volunteers to deal with the problem of garbage in the life circle. In recent years, they have joined the "Water Environment Patrol team", "Coastal Guard" and "Air pollution Patrol Association". All are included in the community independent disaster prevention group ── regularly inspects the river condition and cleans up the silt and garbage in the drainage ditch. When the meteorological bureau predicted that there would be torrential rain, the independent disaster prevention mechanism was activated, and some team members began to take inventory of disaster prevention equipment, while another group of people
