摘要

围绕神木水蚀交错带土壤侵蚀与生态环境演变关系及其整治这一主题，着重讨论系统定位监测研究内容和方法。以典型调查与定位观测相结合，分析研究该地区的气候，风蚀水蚀特征及其生态环境演变过程。通过建立一系列径流观测场和气象站，动态监测不同地形，利用人及水保措施条件下的土壤侵蚀过程，细沟的发展演变，风力特征与风蚀的关系，土壤侵蚀与土壤退化演变。同时结合侵蚀沟，集沙仪，模拟冲刷试验，土壤水分、养分等动态监测，初步建立了一套宏观与微观相结合的动态监测研究体系。首次在风蚀水蚀生态环境脆弱带建立了较为完整的土壤水蚀风蚀生态观测站，获取了一系列宝贵资料，为该区综合治理提供理论依据

Abstract

The crisscross region of water wind erosion is taken as the main research subjects

the relationship between soil erosion and eco environment change has been studied

the subjects and methods of monitoring research have been discussed.Using methods of typical field investigation combined with site dynamic observation

the characteristics of the climate and water wind erosion and eco envirionment evolution process have been analyzed.Through establishing series runoff plots and climate observatory

soil erosion process under varying landuses and topographical thypes in different conservation practices has been monitored

which includes the change of rainfall

runoff

infiltration and soil erosion amount;the evolution of rill erosion;the relationship between wind erosion and wind power;the evolution of soil erosion and soil degradation.The first observatory of water wind erosion and eco environment has been established in the fragile ecologic environment region of the loess plateau in Shenmu county.
