Nonpoint source(NPS)pollutants resulting from land degradation(LD)have been a key influential factor on the deterioration of water quality.Consequently,sustainable land use management(SLM)practices have been employed to reduce the impacts of LD globally.However,the adoption of SLM practices is often not effective to protect water resources despite its capability of improving water quality.Empirically,evidence shows that activities of land users directly influence SLM practices and NPS pollution of water resources in watersheds,but invariably this has not been clearly understood.Understanding how SLM practices adoption could prevent NPS pollution of water resources in watershed is a necessity.Therefore,the primary aim of the investigation is to comprehend the status of SLM practices with the legal framework supporting the adoption of such practices in the Ashi River watershed.A survey instrument involving structured questionnaire was implemented to collect data.A randomly based lottery method was applied to sample information from 150 land users in two control units’communities.Descriptive and inferential statistics was used to analyze the data.This research revealed that there is low adoption of SLM practices of the study site.The low adoption is due to weak capacity building and enforcement of regulations in the watershed.Occupation and age of the residents are the strongest predictors of SLM adoption rate.Residents connected with farming are more sensitive to the adoption status of SLM.It is our recommendation that policy makers should ensure capacity building,and enforcement of regulations can specifically compel farmers to adopt SLM technologies.This approach would complement other strategies to solve the NPS pollution issue of Ashi River. 展开更多

该研究以北京顺义区为例,分析农业土地资源所承受的压力;在DPSIR框架下设计25个指标,系统评价1991-2002年间农业土地资源"驱动力"、"压力"、"状态"、"影响"、"响应"指数的时空特征... 该研究以北京顺义区为例,分析农业土地资源所承受的压力;在DPSIR框架下设计25个指标,系统评价1991-2002年间农业土地资源"驱动力"、"压力"、"状态"、"影响"、"响应"指数的时空特征。时间变化上,顺义区农业土地利用变化的"驱动力"和"压力"逐步增强;系统的"状态"和"影响"呈不规则下降趋势;"响应"水平在2000年以前变化平稳,之后快速上升。空间分布上,"驱动力"高值区分布在城市化和工业化水平较高的区域,"压力"高值区分布在农业集约化水平较高的区域,系统的"状态"和"影响"具有空间"互补"的特点,"响应"与"驱动力"的空间分布基本一致。适度发展工业和城市,科学施肥与养殖、降低农业土地利用的环境影响,调整种养结构,建立"节地、节水"型农业,改善农业发展条件和提高农业土地经济产出是提高农地资源持续利用水平的有效措施。 展开更多
