耕作对坡耕地水土流失和冬小麦产量的影响

Shuitu Baochi Xuebao, 2006
在模拟降雨和自然降雨条件下研究长期（6年）定位耕作措施对豫西早区坡耕地水分保持、土壤流失以及冬小麦产量的影响。耕作措施包括少耕、免耕覆盖、深松覆盖和常规耕作。田间模拟降雨试验用来测定不同耕作措施对径流和土壤流失的影响，自然降雨小区主要用来验证模拟试验结果，同时测定不同耕作措施对冬小麦产量的影响。模拟试验结果表明：不同耕作措施下的土壤饱和导水率没有明显差异，雨前土壤含水量和降雨强度均显著影响地表径流。在试验条件下，免耕覆盖处理未产生径流和土壤流失，水土保持效果最好。与常规耕作比较 ...

国家重点公路重庆奉云段高速公路水土保持措施的探讨

Shuitu Baochi Xuebao, 2006
在对重庆奉云段高速公路工程特点、施工工艺深入分析并类比其他地区实测数据的基础上，对高速公路水土流失防治责任范围进行了准确界定，并充分考虑了路线经过区诱发性滑坡、泥石流影响及潜在危险性．提出了包括主体工程防护、新增水土保持措施及诱发性滑坡、泥石流预警防护三位一体的高速公路水土保持措施体系，并对高速公路建设中水土流失强度大的弃渣场进行了分类典型设计。

海南屯昌砂质壤土橡胶林水土保持措施生态产品能值分析

Shuitu Baochi Xuebao
目的针对海南省橡胶林区水土流失严重且治理措施效果评估不足的问题，通过能值分析方法，系统评估不同水土保持措施的生态产品特征及可持续性，为优化措施配置提供科学依据。方法利用海南省屯昌县设置7个径流小区2 a的观测结果与2001—2020年降雨数据，基于能值分析理论，评估全生命周期单一措施（带状绿肥覆盖T1、蓄水沟T2、水平阶T3）及组合措施（蓄水沟+带状绿肥覆盖T4、水平阶+蓄水沟T5、水平阶+蓄水沟+带状绿肥覆盖T6）的能值投入与生态服务（水源涵养、固持土壤、肥力保持）产出，量化全生命周期能值产投比 ...
