我国南方当前水土流失与生态安全中值得重视的问题

Some Considerations for Present Soil and Water Conservation and Ecology Security of South China

根据实地考察,提出我国南方8省当前水土流失及生态安全存在10个值得重视的问题。其中前5个是水土流失现状与问题,诸如,整体好转,局部恶化;远看青山在,近看水土流;生态安全问题凸现;治理经验不少,但效益局限;农村水保,治理应当先;后5个问题是水土治理措施与途径,诸如;国家扶持,地区自立;开发治理,经济生态优先;防治规划,战略推进;政策法制,配套实现;科技领先,体系周全。所有这些问题,对该区当前水土流失治理均有重要的指导意义,可供有关方面参考。

According to field surveys, ten issues on soil and water conservation and ecology security in the eight provinces of south China are discussed. The former five are dedicated to elucidate the present status and problems of soil and water conservation. In general, the status of soil and water conservation turns better but still worse in part. Such a phenomena is presented that the hills are green with soil and water loss remaining. Problems of ecology security related to soil and water conservation are severe. Experience for soil and water conservation is not efficient in practice. Soil and water conservation in the rural areas is necessary and should be put ahead. The latter five attempt to summarize the control and mitigation measures of soil and water conservation. These items include national support, regional self-help, exploitation and conservation, ecological economy, planning, strategy, policy, cooperation, science and technology and integrated system. The discussion is expected to provide a guide and reference in rail and water conservation for decision-makers.
