The forest was characterized with phanerophyte evergreen plants with single-mesophyll-leathery leaves, which reflected the nature of tropical Karst mountainous seasonal rain forest.(2). Community succession was divided into five stages by using Cluster method, PCA method; the succesion stages include herbaceous stage, scrub-shrub stage, small tree stage, arbor stage and climax seasonal rain forest stage.(3). Based on similarity theory, succession sere was constructed with the community similarity equation formed.

结果表明：(1)森林群落在外貌上，以常绿高位芽、单叶、革质、中型叶植物为主，反映了热带岩溶山地季雨林的特点；(2)运用聚类分析、PCA排序等方法将群落演替阶段划分为草本群落阶段、灌丛阶段、小乔木阶段、乔林阶段、顶极季雨林阶段；(3)运用相似学原理，组建群落间相似度方程并以此方程构建了群落演替系列；(4)研究表明桂西南岩溶区生态系统健康受到严重胁迫。

Therefore this dissertation studies the macrocosmic evaluate methods of bus priority planning based on the contents above, and constitutes a set of evaluation indexes using the managers, users and relatives as the main bodies of the plan evaluation. It filters a more relative indexes by the method of independent minimum variable fuzzy cluster analysis and analyzes the calculate methods of the chosen indexes.

The injective rings play an important role in the study of rings and categories of modules . First , we introduce the notion of ann-injective rings and CT-injective modules .Second,we make an inquiry into a series of their properties.Third,we give the definition of homological dimension of CT-injective modules.At last,we give the definition of FGT rings which is the extension of cogenerator rings.

本文对环与模范畴中一重要的模类—内射模进行了延拓，引入了ann -自内射环以及CT -内射模的概念，探讨了它们一系列的性质，并定义了CT -内射模的同调维数，最后对余生成子环进行推广得到了FGT -环，讨论了它与CT -内射环的关系以及它的一些性质。
