1960—2020年东北黑土区水蚀动力因子时空格局及其对主要大气海洋环流模式的响应

Shuitu Baochi Xuebao
[目的] 研究东北黑土区水蚀动力因子的时空格局及其对大气海洋环流模式的响应,对区域极端降水事件诱发的土壤侵蚀防治有重要意义。[方法] 选用降雨侵蚀力(R)、暴雨雨量(R50p)、极端强降水量(R95p)、连续5日最大降水量(R5d)表征水蚀动力因子,基于1960—2020年逐日降雨数据,采用滑动平均、小波分析、Sen斜率估计法、Mann-Kendall检验方法,分析1960—2020年东北黑土区水蚀动力因子的时空格局,解析水蚀动力因子对大气海洋环流模式的响应。[结果] (1)东北黑土区的年降雨侵蚀力(R)

东北黑土区水土流失的经济分析与政策改进 = Economic analysis and policy improvement on soil erosion in the mollisols region of Northeast

, 2010
水和土地是人类赖以生存的根基和最重要的农业资源。中国东北黑土区是世界仅存三大黑土带之一，拥有地球上最珍贵的土地资源。近年来，该区域水土流失问题日趋严重，引起了广泛关注和高度重视。对这一问题的治理，也已纳入中央和地方政府的重要日程。Master of Public ...

长期施肥对大豆地土壤蒸发和水分利用效率的影响

, 2009
以中国科学院海伦农业生态实验站长期定位试验为研究平台,利用Micro-lysimeter法,研究了东北黑土区不同施肥管理对大豆地土壤蒸发和水分利用效率的影响。结果表明:长期施肥通过改变土壤的水分物理性质和作物叶面积指数,进而调控土壤蒸发,不同处理间土壤蒸发表现如下:无肥(F1)>单施化肥(F2)>化肥+有机肥(F3);大豆不同生育时期土壤蒸发强度表现为:开花期-结荚期>子叶期-开花期>出苗期-子叶期>鼓粒期-成熟期>结荚期-鼓粒期,同时土壤蒸发强度与土壤表层含水量间呈显著正相关;在不同施肥管理中化肥 ...
