摘要
本文分析了黄土丘陵沟壑区土地演化中三种能流形式所引起的地理过程,运用多元非线性回归的数学方法建立了三川河流域光能趋势面方程,进而论证了该区两次能量耗散过程与土地结构格局的关系。
The paper analyzied the geographical process beacause of three kind of the coaversion of energy on land evolution in loess hills and gullys region, and used the mathme tical method of the polybasic-ualinear regression to set up light-energy tendency equntion in three river basin; the author disscussed the relntionship between the dissipntion process of level and vertical direction energy and land structure in the area.
