湘赣两省水土保持工作调查报告

林地是两省水土流失的主要源地之一。林地水土流失年侵蚀量占总侵蚀量湖南为３０％～４０％，江西为４０％～５０％。其原因是乱砍滥伐、全垦造林、经济林垦复、针叶纯林比例过高等；坡耕地水土流失年侵蚀量占总侵蚀量湖南为４０％～５０％，江西约为１０％；开发建设活动引起的水土流失问题日趋严重，重力侵蚀也不容忽视。主要对策是：实施坡改梯工程，解决农民的基本农田；把林地纳入水土保持监督管理之中；强化对开发建设活动的监督管理，全面实施水土保持法；加强水土保持科研工作等。

A Survey Report on Soil and Water Conservation of Hunan and Jiangxi Province

Forestland is one of the main sources for soil and water loss of Hunan and Jiangxi provinces. The amount of annual erosion of water and soil loss makes up 30%～40% in Hunan Province and 40%～50% in Jiangxi Province of that of the annual tltal. The reasons are destructive lumbering and felling, total reclamation and afforestation, multiple reclamation of economic trees and excessive proportion of unmixed coniferous trees. The annual erosion of soil loss of slope land makes upabout 40%～50% in Hunan and about 10% in Jiangxi province of the tltal annual erosion. In addition, the soil and water loss caused by development and construction activties becomes severely day by day and the gravity erosion should not be ignored. The main countermeasures are to change slope land into terraces, provide farmland with high productivity for farmers, bring forest land into monitoring and management of soil conservation, strengthen the monitoring and management in the activities of development and construction, implement Soil and Water Conservation Act in an all-round way and speed up the elementary scientific and technical work of soil conservation.
