摘要

近50a来

我国水土流失(含水蚀、风蚀)总面积呈抛物线形发展态势

水蚀趋势亦然

但风蚀面积则呈连续增长趋势

发展形势较为严峻。强调指出领导重视、科学政策的制定和落实、依靠科技、小流域综合治理、农村经济改善、农村能源得到缓解等

是我国治理水土流失由破坏大于治理到治理大于破坏

走向健康发展的新阶段的重要因素。

Abstract

In recent 50 years

China total area of soil and water loss(water-erosion and wind-erosion) develops as a parabola type trend

and water erosion is the same as former.Area of wind-erosion in China increases continuously and their situation is serious.It is emphasized that official recognition

establishment and fulfillment of scientific policies

relying on science and technology

comprehensive control in small watershed

development of rural economy and replacement of rural energy source supply are important factors that the speed of comprehensive control of soil and water loss is faster than the destruction and to reach a new stage of healthy development of environment.
