摘　　要：选取太原市小返乡30年枣树林地、30年苹果园地和草地样地,结果表明测量地点轻度甚至重度土壤干层发育。除地形、气候和植被类型外,土壤特性也是影响土壤干层发育的重要因素。因此,生态恢复要根据土壤干层发育情况,并遵循植被演替的自然规律。Mlo woodland,apple garden and nature grassland growing for over 30 years in Xiaofan country,Taiyuan were selected.The results indicated that the soil had light or serious development of dry layers.The development of dry layers was universal in the soil of Xiaofan Country of Taiyuan.Besides terrain,climate and vegetation,soil characteristics had exerted great impacts on the development of dry layers.Therefore,according to the soil dry layer,ecological recovery should follow the development conditions of vegetation succession of nature.
