摘要
长江中游地区水土流失日益加剧,尤以江南红色丘陵区最为严重,素有“江南红色沙漠”之称。产生流失的主要根源是对森林的过度采伐和不合理的农林耕作制度。其治理途径应是:以农村能源建设为出发点,以稳定粮食生产为基础,大力改造和开发利用现有林业用地、荒山荒坡和侵蚀劣地,增加林草植被,改善生态环境,促进农村经济发展。
Soil loss in the middle area of the Yangtze River is increasingly severe. The red hilly region in south of the Yeangtze River is especially severe, which is usually called 'the red desert in the south of the Xangtze River' The main cause of soil loss is overcutting of forest and irrational .cultivation system of agriculature and forestry. The way of harnessment is by taking rural energy construction as the starting point and taking stable grain production as the foundation, to improve, develop and utilize the existing forest land, waste mountains and sloping land; and eroded inferior land, to increase the vegetation cover and to improve the e-cological environment to promote the rural economic development.
