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.

以某烧结机脱硝项目中运行6个月的中温SCR脱硝催化剂为研究对象,利用酸洗方式对失活的催化剂进行再生,在模拟烧结烟气条件下,对比了失活催化剂、再生催化剂和新鲜催化剂的脱硝活性,并通过XRF、TG、BET等检测手段对催化剂、堵塞物和烧结飞灰进行了表征.结果表明,在300℃以上温度运行,可有效避免硫酸氢铵对催化剂的不利影响;碱金属和重金属的共同作用使得催化剂活性位点减少和比表面积下降,导致催化剂灭活,其中碱金属中毒是催化剂失活的主要原因.
