The effect of water state of soil on eco-boundary over leaf surface was disscussed by takingPopulus davidiana as experimental material. The results show that to change soil water state by some methods was to adjust and control the
forming quality of eco-boundary in fact. The plant in good water condition must be accompanied by thinner eco-boundary. This
eco-boundary is beneficial to exchange and flow of the substances between plant and environment.

I "trod notionClimate warming is one of the most serious environment problems. It is sure that the present elevation of COZ and other greenhouse gases such as CH4,NzO, Of induced by human activities were makingglobal climate to go through inexperienced changes(Zhao et al. 1998i Wu 1989). The ecosystems distributed in high latitude area were likely to experiencemuch bigger change according to some previous researches (Shetwood 1983). This is the main reasonthat we focus on effects of possi… 相似文献
