摘　　要：黄土丘陵是黄土高原的主要地貌类型．一些基本生态环境因子，如太阳辐射、气温和土壤水分会受到丘陵地貌的影响而发生分异，同时对农业而言，这些因子的变化也会影响丘陵地形的利用方式．据此，我们对不同坡向和不同坡位上的太阳辐射、气温、土壤温度和土壤水分进行长期定位观测和较为系统的分析，其结果将有助于黄土丘陵坡地资源的合理开发和利用。The loess hill is main one of the landform types in the Loess Plateau,China. The ecovironmental elements, like the solar radiation ,air and soil temperature,,air and soil moisture couldcause some difference by the influence of the hilly land forms. Meanwhile, thathat differences willeffect the utilizing way. On the above base, the eco-environmental elements of the differentdirections of the slopes have been observed on the same points over a long period of time,and theresponse of their distribution to the hilly landform has been researched systematically. The resultsof this present paper could provide some ecological base for the rational exploitation and utilizationof the loess hilly slope land in the Loess Plateau.
