摘要
江西是我国南方水土流失较严重的省份之一,水土流失造成农业生态环境恶化,成为江西社会经济可持续发展中的一个主要制约因素。用遥感技术,结合全球定位系统、地理信息系统进行水土流失调查是目前国际上比较先进的方法。本文应用“3S”技术,对江西省水土流失的现状进行了调查,总结了其遥感特征和空间分布规律,论述了水土流失对江西经济社会发展的危害,进而提出了水土流失的防治对策。
Jiangxi is one of the provinces in South China where soil erosion problem is serious,resulting in deterioration of agricultural ecosystem,which is a major restrictive factor for the social and economic sustainable development in Jiangxi.Remote-sensing technique(RS)combined with global positioning system(GPS)and geo-graphic information system(GIS)is currently an advanced method in the world to investigate soil erosion.Using the so-called“3S”technique as mentioned above,the authors have investigated the present situation of soil ero-sion in Jiangxi,shed lights on the remote-sensing image features and spatial distribution pattern of soil erosion,explained the harmful effect of soil erosion on social and economic development of this province,and finally worked out some preventive and treatment measures.
