Water resource area Phyllostachys heterocycla forest structure adjustment method for controlling non-point source pollution

Abstract

A water resource area Phyllostachys heterocycla forest structure adjustment method for controlling non-point source pollution belongs to the technical field of non-point source pollution control and ecological engineering. The method includes the following process steps: 1) plant allocation: selecting shrubs and small arbors which grow up locally, have economic value, and are shade-tolerant, performing forest stand plant allocation, establishing a multi-specie multi-layer multifunctional forest stand structure, increasing the biodiversity of a Phyllostachys heterocycla forest, and improve the water resource conservation ability of the water resource area Phyllostachys heterocycla forest and the water quality; 2) forest establishment: selecting healthy and strong nursery stocks to be planted; and 3) management: performing weeding and pruning in the early stage of the Phyllostachys heterocycla forest, performing water and fertilizer management before planting, and performing management after planting. The water resource area Phyllostachys heterocycla forest structure adjustment method for controlling non-point source pollution is reasonable in design, can adjust the forest stand structure of the water resource area Phyllostachys heterocycla forest structure, can increase the biodiversity of the Phyllostachys heterocycla forest, can improve ecological functions such as water and soil conservation and water resource conservation, can facilitate non-point source pollution control and water environment protection.

Description

technical field [0001] The invention belongs to the technical fields of prevention and control of non-point source pollution and ecological engineering, and in particular relates to a method for adjusting the structure of moso bamboo forests in water source areas for the prevention and control of non-point source pollution. Background technique [0002] The intensity of human activities in the forest land in the water source area is relatively low, and the vegetation coverage rate is high, which can effectively slow down the erosion of the rainwater on the surface. Compared with other non-point source pollution, the pollution load is lower, but improper management will make the forest land a certain extent. an important source of pollution. [0003] Moso bamboo grows fast, has a short harvesting cycle, matures early and has high economic value. It is widely distributed in southern water source areas and is one of the representative economic forest types in subtropical region...
