水土保持林草防护体系,是籍助于生物学的某些原理,营造一定组成和结构的森林和草场的群体。借以达到拦蓄暴雨、减缓径流、固结土壤、防止侵蚀、减少河流泥沙、调节枯洪、预防水旱灾害,并生产出一定的林牧产品的目的。它是发展农业,治理江河的重要措施之一。 江西山地资源丰富,气候条件优越,有利于植物的生长发育。但是由于过去一直未能对影响农业生态和多种经营的植被予以应有的重视,致使我们今天面临了:森林资源遭到惊人的破坏,每年采伐量超过年生长量,森林木材蓄积量逐年下降;水土流失日益严重。据有关部门资
Soil and water conservation forest and grass protection system is based on certain principles of biology, to create a certain composition and structure of the forest and grassland groups. So as to achieve the purpose of intercepting heavy rainfall, slowing runoff, consolidating soil, preventing erosion, reducing river sediment, regulating floods, preventing floods and droughts, and producing certain forest and animal husbandry products. It is one of the important measures to develop agriculture and control the rivers. Rich in mountain resources in Jiangxi, climate conditions are superior to the growth and development of plants. However, due to its failure to pay due attention to the agro-ecological and diversified vegetation in the past, we are facing today: the astonishing destruction of forest resources, the annual volume of logging exceeding annual growth and the declining volume of forest timber ; Soil and water loss is increasingly serious.
