Plant Hydraulics Schemes
Ecosystem Demography Model (ED) V2.2，看到这里并且感兴趣的朋友应该不需要我再做介绍了，可以阅读一下模式的特性文章GMD-ED2。
Prof. Xu 对ED2进行了基于plant hydraulics理论的模块扩展，简称ED2-hydro，相关文章可以参见：Diversity in plant hydraulic traits…和Variation in tropical forest canopy water content…。
关于Plant Hydraulics[PHS]的模式理论，可以参见Noah-mp-PHS(capacitance): Overview of Plant Hydraulics Model。
