摘要
在ＡＲＣ／ＩＮＦＯ 和ＡＲＣ／ ＶＩＥＷ 地理信息系统的支持下，对构成生境的基本要素图形数据库进行叠加分析，研究了西双版纳纳板河自然保护区的生境格局．然后，运用Ｂａｙｅｓ 决策和模糊数学中的隶属度的概念，试图定量化描述生境格局与印度野牛生存的关系．结果表明，目前印度野牛生境适宜区对热带季节雨林生境类型的适宜性概率为０ ．２９２ ，对亚热带季风常绿阔叶林生境类型的适宜性概率为０ ．６ ，对亚热带苔藓常绿阔叶林生境类型的适宜性概率为０ ．１０８ ；
With the support of ARC/INFO and ARC/VIEW, the graphic data on the basic elements of ecotopes were overlapped and analyzed, and the ecotope patterns in Nabanhe Nature Reserve of Xishuangbanna were identified. Based on these, the relationship between the ecotope types and the habitas of Bos gaurus readei was analyzed with the applications of Bayes decision and subordination degree of fuzzy mathematics. The result shows that the probability of the suitability for Bos gaurus readei was 0.292 in the tropical seasonal rainforest habitat type, 0.600 in the subtropical monsoon evergreen broad leaved forest, and 0.108 in subtropical bryo evergreen broad leaved forest, which suggests that the damage of tropical forest had threatened the habitat of Bos gaurus readei.
