摘要:
“万物土中生”,土壤是生态环境的重要组成部分.探讨退耕还林(草)工程对土壤质量的影响,可以为工程的持续开展提供有关的理论依据.通过对我国退耕还林(草)工程重点试验县—青海省大通县北川河流域不同时间序列的退耕地的土壤,进行了系统的对比研究.研究结果表明:土壤质量综合指数值为坡耕地34.0%<弃耕地40.8%<退耕地(310a)63.6%<退耕地(1120a)74.4%<天然次生林地82.8%<天然灌丛地90.6%.随着时间的延续,退耕地土壤理化性质将会得到明显改善,土壤质量会逐步得到提高.
Abstract:
"Anything grows in soil" and soil is an important part of the ecological environment.The study on the influence of the Project of Changing Slope Farmland into Forest and Grassland on soil quality could provide academic bases for the project development sustainably.Through the study on soil of the time sequence rehabilitation land in Beichuanhe watershed of Datong county,Qinghai province,one of the national experimental counties for the Project of Changing Slope Farmland into Forest and Grassland,the results showed that the soil quality index of different land types is sloping land 34.0%
