山区水土流失防治与土地资源持续利用关系探讨

山区水土流失与土地利用的关系非常密切.不仅因为水土流失的发生和发展从根本上是人类不合理开发利用土地资源的行为所致,而且,水土流失的日益严重又直接影响和制约着土地资源的可持续利用,进而危及山区经济社会的可持续发展.本文提出了水土流失山区土地资源可持续利用的特定内涵,水土流失防治必须以土地资源合理利用为前提.针对以往土地利用规划与水土保持规划各自为政的弊端和教训,应当着眼于土地合理利用与水土保持措施的有机结合,把土地利用规划与水土保持规划"合二为一",以实现水土流失山区土地资源可持续利用和山区人地关系的协调发展.

Sustainable Use of Land Resources and Soil Erosion Control in Mountainous Areas

The relation between soil erosion and land use in mountain areas is very close, and both of them are in causality: soil erosion is fundamentally the inevitable result of land resources irrational exploitation, while increasingly serious soil erosion immediately influences and restricts the sustainable use of land resources, and then endangers the sustainable development of the economy and society in mountain areas. The authors put forward the particular connotation of sustainable land use in mountain areas based on the reasons mentioned above, and consider that soil erosion control must depend on the rational land use, and the leading countermeasure for land resources rational exploitation in mountain areas is to control the soil and water loss. For a long time, land use planning as well as soil and water conservation planning were each done in its own way, and the effects of planning were not so good. The authors consider that rational land use pattern, structure and corresponding soil conservation measures should be combined organically and be planned simultaneously, which means to combine land use planning with soil and water conservation planning into one (i.e. comprehensive land use and soil conservation planning), consequently the objectives of sustainable use of land resources and the coordinated development of human beings and nature in mountain areas would be realized.
