报告内容简介:
(Transpiration modelling) Transpiration is often modelled from potential transpiration (the rate under the optimal moisture condition) reduced by some scaling functions reflecting the effects of selected environmental stress. In this part of presentation, I will briefly talk about a hybrid dual-source energy partitioning model for estimating potential transpiration, discuss some recent advances in selecting and parameterising scaling functions, and introduce a new physiologically-based SPAC model. (Groundwater recharge) Understanding and quantification of changes in groundwater recharge after surface vegetation alteration are important not only for water resource management, but also for land-use and land-cover management. Application of simple chloride mass balance (CMB) method over areas of historical forest clearance, or recent plantation, suffers from two difficulties: pre-clearance (or pre-plantation) recharge may have been contaminated by recharge that occurred after forest clearance (or plantation); and the post-clearance (or post-plantation) recharge may not yet have reached new chloride equilibrium. This part of presentation will discuss some recent method development to address these difficulties.
