摘要
为研究不同土地利用类型在石漠化地区的治理效果,以云南典型石漠化官麦地小流域为研究对象,多角度出发,运用综合评价函数、SPASS软件辅助评价水土保持综合治理效益,对石漠化小流域水土保持综合治理效益进行分析。研究区水保林、经果林、梯地的土壤侵蚀量少于荒山草地,能有效保护和改良土壤,增加土壤肥力,水土保持综合治理效益综合分值为58.76,水土保持综合治理效益等级为中等。综合分析表明:不同土地利用类型中,水保林、经果林、梯地能有效改善小流域内的生态环境条件和生产条件,提高当地农作物经济产量,2020年流域内人均可支配收入为3854元,较治理前3424元提高12.56%,农民生活水平和消费能力明显提高。研究成果为全面衡量西南石漠化地区水土保持治理效果提供方法借鉴,推广意义较大。
In order to study the control effect of different land use types in rocky desertification area,the governance effect of Guanmaidi small watershed in yunnan typical rocky desertification officer small watershed as the research object,the multiple perspectives,using a comprehensive evaluation function,SPASS software support evaluation of comprehensive harness of soil and water conservation benefits,small watershed comprehensive harness of soil and water conservation benefit of rocky desertification were analyzed,and the following conclusions:The soil erosion amount of water conservation forest,fruity forest and terrace is less than barren grass,which can effectively protect and improve soil and increase soil fertility.The comprehensive benefit score of water and soil conservation is 58.76,and the comprehensive benefit grade of water and soil conservation is medium.Comprehensive analysis show that different land use types in soil conservation forest,economic forest,terrace can effectively improve the ecological environment of the small watershed in conditions and production conditions,improve local economic crops production.In 2020,per capita disposable income in the basin was 3854 yuan,an increase of 12.56%compared with 3424 yuan before governance.The living standards and consumption power of rural residents have improved markedly.The research results of this paper provide a reference for comprehensively measuring the effect of soil and water conservation control in southwestern rocky desertification area,and have great significance in popularization.
