Estimation of forests'' ecological water requirement based on agrometeorology:Taking Jinghe Watershed as an example
基于农业气象学原理的林地生态需水量估算——以泾河流域为例

Jinghe is the second-branch of the Yellow River with the length of 450km and the watershed is about 45421 km~2. For the sake of dry climate and human activities, there are only thin vegetation there. The serious soil and water loss caused by degraded vegetation ecosystems is one of the most serious regions of soil and water loss in the Loess Plateau and one of the main silt sources floating in the Yellow River. Therefore, the research on ecological water requirement in the watershed will be important to the...
