坡形是一类重要的立地因子,坡形因素的生物生态学效应国内从未涉及。研究了麻疯树基地不同坡形因素对个体形态、生物量及其器官配置、群体生产力与种子生产的影响,并用生活史权衡法则解释了坡形异质性对生物量及其配置的塑造作用,从资源配置上认识了干枝比例降低与内部配置优化从而提高种子产量的树体管理原理,并从基地高产稳产上提出了凸坡、平地水分调控思路与措施。

The slope form is an important site factor in nature,but no discussion has been made on its biological and ecological effects within our country.This paper deals with the influences of the slope form factor in the Jatrophas curcas base on individual phenotype,biomass and its organ allocation,population productivity,and seed production,explains the functions of slope form heterogeneity of five types of sites（convex slope,level land,gradient sloping land,gentle sloping land,and micro-convex slope） on the biomass and allocation by tradeoff law of life history theory,indicates the tree management principle of decreasing the proportion of trunk and branch,and optimizing the internal resource architecture of individual,and then improving the seed production in terms of resource allocation,and proposes the ideas and methods of moisture control for convex slope and level land from the viewpoint of high and stabe yield.
