Embodiment

[0046] What this embodiment is aimed at is an area of ​​14.28 hectares, wherein cultivated land area is 11.08 hectares, woodland area is 1.39 hectares, other agricultural lands are 0.79 hectares, and the rest is the area of ​​river surface. Most of the area is vegetable land and some nurseries. The west side used to be a pit pond, but now it is a weed land. The current terrain is low-lying. There are no economic crops, no irrigation and drainage facilities, and about 100 mu of high-quality farmland will be formed through renovation; the east The side is an ecological conservation forest, adjacent to the Xiangyang River. The terrain is relatively flat, and the forest is relatively single. The main direction is cedar trees. Camphor and Metasequoia poplar forests are planted in rows, and there are a small amount of bamboo forests in the riverside area. The construction process of each processing unit is as follows:

Abstract

The invention discloses an agriculture and forestry wet composite ecological purification system. The system comprises composite ecological purification units such as an ecological hydroponic area, aclear water conservation area, an overwater forest area and a forest wetland area. Farmland drained water firstly enters the ecological hydroponic area and then enters the clear water conservation area, and part of the drained water serves as a farmland standby water source and part of the drained water enters the overwater forest area. Flooding-resistant tree species are planted in the overwaterforest area, ponds and wetlands are arranged, the ponds are connected through grooves, and the peripheries of the ponds are stacked to form ecological islands; effluent of the overwater forest area enters the forest wetland area, earthwork is properly excavated in a forest, and a multi-stage composite forest wetland formed by connecting ponds and reed wetlands in series is formed; the water outletpart of the forest wetland area enters the river channel. The system makes full use of forest land, wetland and other ecological spaces in an engineering area, constructs an agriculture and forestrywet composite ecological purification system, protects biodiversity, improves the service of the ecological system, and provides basic support for agricultural production and human activities.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to an agricultural, forestry and wet compound ecological purification system, which is suitable for ecological purification of farmland non-point source pollution, protection of biological diversity, and improvement of ecological service functions. Background technique [0002] How to effectively control agricultural non-point source pollution is a bottleneck problem in the process of agricultural development. Before agricultural non-point source pollutants enter the water body, it is an important technical means to control agricultural non-point source pollutants by establishing an ecological interception system to effectively block the output of pollutants such as nitrogen and phosphorus in runoff water. Some related studies have proposed an ecological interception ditch system, which can slow down the flow rate, promote the sedimentation of particulate matter carri...
