水土保持措施布局影响因子的多尺度分析
Multi-Scale Analysis on Impact Factors of Layout of Soil and Water Conservation Measures
摘要
Abstract
Anstract: Taking Changting County of Fujian Province as the research area,the main impact factors of the spatial distribution of soil and water conservation measures are analyzed in different scales from the aspects of natural environment by using statistical methods and GIS technology.In order to avoid the random selection of analysis scale,the characteristic scale of spatial pattern of soil and water conservation measures are identified by wavelet analysis.The scale of 30 m×30 m is used as the basic research unit,and the multiple scale se-quence data layers is based on 30 m scale interval are generated by the average polymerization.The multiple linear regression model in different aggregate size between the soil and water conservation measures and its im-pact factors is constructed.The results show that the impact factors of spatial distribution of soil and water conservation measures have different effect on the spatial distribution of soil and water conservation measures in different ranges of action and different scales,and the influence degree is measured using standard regression coefficient.关键词
