The two tree water consumption characteristics, Populus simonii and Robinia pseudoacacie, and the interactions mechanism with environment factors were both studied at the level of leaf and singletree in terms of the modern technology of heat pulse sap flow and thermal dissipation sap flow probe. The two main purposes of study are to provide the science evidence in estimating the ecologic water consumption rules and to arrange better densities of the two tree species stand.

本文以北京市官厅库区水源涵养林的主要造林树种：小叶杨、刺槐为研究对象，采用当前国内外最先进的热脉冲式树干边材液流测定技术和热扩散式树干边材液流测定探针测定技术，从叶片和单株水平上探讨了刺槐和小叶杨的蒸腾耗水特性以及它们与环境因子之间的影响机理，其结果不仅可为更精确地估计生态用水定额提供科学依据，而且也可为该区域这两种树种的选择及其合理林分的密度起到一定的指导作用。

Two above methods are generalized to tensor product Bézier surfaces and triangular Bézier surfaces, we give two approaches of degree reduction for tensor product Bézier surfaces, each of which reduces a given degree n×m tensor product Bézier surface to a n〓×m〓 one, and two methods of degree reduction for triangular Bézier surfaces, which reduce a given degree n triangular Bézier surface to a degree m one. The explicit formulas of control points for reduced tensor product and triangular Bézier surfaces are obtained respectively.
