中文摘要	[目的]探讨退耕还林还草对土壤质量的综合影响,为半干旱黄土丘陵区退耕地植被恢复与建设提供理论依据。[方法]选择半干旱黄土丘陵区的宁夏回族自治区彭阳县白阳镇中庄村示范区不同退耕地林草植被恢复样地为研究对象,采用AHP决策法对不同林草植被恢复下土壤理化因子进行综合评价。 [结果]土壤水分是影响土壤环境状况的最主要因子,其权重值达到了0.210,其次为土壤的总孔隙度和土壤有机质含量,其权重值分别达到0.136,0.108,同时土壤的毛管持水量、土壤碱解氮含量和土壤脲酶含量也对土壤环境具有十分重要的作用,其权重值分别达到0.085,0.071及0.064。[结论]通过对影响土壤环境的化学性质、物理性质和生物活性的综合评价,认为林地、人工草地和天然草地不同程度地改善和提高了土壤的环境质量,以林地改善程度最大。
英文摘要	[Objective]The effects of grain for green project on soil quality was explored in order to provide theoretical bases for revegetation and reconstruction of abandoned farmland in semi-arid loess hilly region. [Methods]Comprehensive evaluation of soil physio-chemical factors sampled in different revegetated farmlands was conducted by AHP method in the demonstration area at Zhongzhuang village of Pengyang County,Ningxia Hui Autonomous Region of loess hilly area.[Results]Soil moisture was the main factor that affected soil environment,its weighted value reached 0.210.Followed by soil total porosity and soil organic matter content,their weighted values reached 0.136and 0.108,respectively.Meanwhile,soil capillary capacity,soil available nitrogen content and soil urease content had also played very important roles on the soil environment,their weighted values were 0.085,0.071and 0.064respectively.[Conclusion]Through comprehensive evaluation on the environmental impacts in terms of soil chemical properties,physical properties and biological activity,to some degree,woodland,terraces,artificial and natural grassland have been improved regarding to soil environmental quality.Among which,terraced field was observed been improved as the greatest type.
