选取10个主要因子来评判人类活动干扰度及对四川水土流失的影响和响应关系.关联分析表明:载畜量、垦殖指数、人口密度、人均GDP、矿产模数和林地覆盖率是6个关联性最强的人类活动要素.干扰度分析表明:人口压力、过度和不合理的资源开发活动、人为破坏行为是造成水土流失的主要原因.因此解决各类人为逆向活动、规范人类行为是水土保持的首要任务.为此,在新的历史时期,水土流失的防治是建立在一种生态系统方式基础之上的防治,是一种可持续发展的管理策略.这种方式的基础是在水土流失防治的宗旨、观念、方法和领域方面予以系统创新和突破,从理念层次、政策层次、空间层次、技术层次和模式层次上同步跟进;从治理策略上进行系统整合.
Ten main factors were selected to judge the degree of human disturbance and its impact on the soil erosion in Sichuan Province.Relationship analysis showed that there were 6 associations of stocking capacity, cultivation index, population density, GDP per capita, mineral modulus and forest cover The strongest human activities elements.The analysis of interference shows that: population pressure, excessive and unreasonable exploitation of resources and man-made sabotage are the main causes of water and soil loss.Therefore, to solve all kinds of anthropogenic reverse activities and to regulate human behavior is soil and water conservation Therefore, in the new historical period, the prevention and control of soil and water loss is based on an ecosystem approach to prevention and control and is a sustainable management strategy based on the concept of soil and water loss We should systematically innovate and make breakthroughs in the purpose, concept, method and field of prevention and treatment and simultaneously follow up from the concept level, the policy level, the space level, the technical level and the mode level; and carry out systematic integration from the governance strategy.
