石漠化的地质指标体系

Geoindicator system of karst rocky desertification

分析了岩溶石漠化地质指标的概念和特征,从影响石漠化环境的自然因子、人文因子,石漠化发育分布现状和所引发的后果或危害中提取相应的指标,依照影响(Cause)-状态(State)-后果(Result)框架构建了石漠化地质指标体系。探讨了石漠化地质指标的研究内容,包括指标的研究意义、指标变化的原因和指标监测的空间尺度、时间尺度、测量方法。

This paper studies the concept and characteristics of the geoindicators of the karst rocky desertification.The geoindicators are chosen from the influence factors of the natural environments and human activities causing karst rocky desertification.According to the framework of Cause-State-Result,the authors have set up the system of rocky desertification geoindicators and discussed the research contents of rocky desertification geoindicators,which include significance of research on each rocky desertification geoindicator,human or natural causes of geoindicator change,spatial scale of monitoring,methods of measurement and frequency of measurement.
