From the point of view of geobotany, with the method of correlative factors of growth of plants, a countrywide theoretic ecological division was done for the introduction of Camptotheca acuminata and three kinds of areas of ecological preferent zone, ecological adaptive zone and ecological unadaptable zone were divided. With the theory of synecology, the characteristic on environment, constitution, life form spectrum, diversity, similarity of plots of communities were researched. Applying the method of species association, discrete distribution, indensity index, fractal geometry, etc. to research relations between the species of the communities, space distribution of Camptotheca acuminata, structure of age of Camptotheca acuminata, in different communities. Using the theories of autoecology, distibutons of seeds on land and growth of seedlings in vertical and horizontal directions, biomass of organ of Camptotheca acuminata were analyzed. On the opinions of conservation biology, the external and internal factors impressing Camptotheca acuminata were analyzed to research the mechanism of the endangered species, and with using of CTM Model, the future development direction of Camptotheca acuminata in different communities were forecasted, and. Standing on the position of resources ecology, discussing the regularity of camptothein in Camptotheca acuminata of different sites and seeding of different resources, also the the derive technics of camptothecin.

本文从地植物学的角度，运用植物生长相关因子法，对我国喜树资源的生态适宜区进行了划分，理论上确定了我国的喜树的引种栽培的最适生活区域、生态适宜区域和不适宜生活区域；从群落生态学的角度，对野生喜树所在的典型群落的群落环境、群落组成、群落生活型谱、群落的物种多样性特点、群落样地间相似性进行了研究；从种群生态学的角度，运用种间联结性、离散分布模型、聚集强度指数、分析几何等分析手段，对野生喜树所在典型群落间的种间关系、喜树的空间分布格局、年龄结构等进行了分析；从个体生态学的角度，对不同年龄组的喜树的种子的散落的垂直分布、水平分布、时间分布及种子发芽率和千里重等特点、不同种源的人工喜树苗期特点、喜树的高生长和茎生长特点、喜树的器官生物量特点进行了研究；从保护生物学的角度，对野生喜树的濒危的内部因素和外部因素进行了探讨，并运用CTM模型对不同群落中野生喜树的种群趋势进行了预测；从资源生态学的角度，对我国地理环境下喜树中喜树碱含量的地理分布规律、不同种源的喜树幼苗中喜树碱含量变化规律进行了研究，并对喜树碱的提取工艺进行了探讨。

The loose interspecific association is possibly related to the development stage of communities and ecological features of species.

这种"松散"的状况可能与群落的发展阶段和物种的生态学特性有关。

According to the phytosociological theories and methods of Braun-Blanquet's school, the regional savanna vegetation of the dry-hot valleys of Yuanjiang river had been investigated. Based on the principle of fidelity degree, the typical 110 releves taken from every sampling stands of the dry-hot valleys were sorted up from below to upper into 15 Associations, then into 5 Alliances, 2 Orders and 1 Class. A synoptic classification system of Class-Order-Alliance-Association was established for the purpose to reflect deeply the characteristics of all syntaxa there in the aspect of plant component and their abundance-dominancy, presence, cover coefficient, life form, growth form, and ecological environment, community structure, species types and so on.

采用Braun-Blanquet植物群落学研究的理论与方法，对云南元江中上游干热河谷分布的植被进行考察研究，把各处取得较典型的110个样地记录按确限度的原则由下而上归类成15个群丛、5个群属、2个群目和1个群纲，建立了元江干热河谷萨王纳植被群纲—群目—群属—群丛分类系统综合表和15个群丛表，以全面深入反映全干热河谷植物群落各级分类单位中各植物种类组成的多优度、存在度、盖度系数、生活型和生长型等特征及其群落结构、生态环境和种型类别。
