4、rachypithecus franois) is the endangered and protected species around the world and it distributes restrictedly in Guangxi, Guizhou, Chongqing in China and northern Vietnam. It has been defined the First-Class National Protected Species in China and Endangered-Class in the world. Habitat fragmentati

Based on 3S technology, we analyzed landscape pattern and habitat fragmentation of franois langur, revealed the relationship between human activities and habitat fragmentation, and analyzed habitat restoration by GIS simulation, which is a scientific referen
6、ce for franois langur protection and management. The study areas include Longzhou, Fusui, Daxin, Longan Buye, Longan Qunxu, Debao, Jinxi Yuexu, Jinxi Nanpo, Jinxi Xinxin,Longlin in Guangxi province and Mayanghe natural reserve, Daozhen natural reserve in Guizhou. The main results are as following: 1
7、 The habitat landscape pattern of franois langur was studied by means of TM remote sensing image, electron map and relief map as the main information source and GIS as the main tool. 2 We analyzed the main index of landscape pattern and habitat fragmentation of Longzhou, Fusui, Daxin, Longan, Debao,

11、s human impact sources, and natural areas within a 400m distance as disturbance area. Through analyzing, we find the fragmentation index of disturbance area is higher than the natural area, and the Karst forest proportion is lower, so we IV think human activities is the major reason for habitat frag
12、mentation of Franois Langur. 4 Theoretically, if we want to resume the habitat, the first job is to resume the submontane farmland and build up corridors between every karst hills, then the whole area is constitute by karst forest. We analyzed the joint value and obdurate value by buffer function of
13、 GIS, which is a reference for habitat protection and management. 5 We analyzed latency habitat of Franois Langur by its habit, geological condition, vegetation and historical distribution, we find that feasible latency habitat is 321623 ha, which is 11 times more than present habitat, and only the
14、present habitats of Longzhou, Daxin, Debao are contained by feasible latency habitat, which illuminated hunt and other human impact affected Franois Langur heavily and habitat has strong enlarge potential. 6 We suggest set up a habitat programming: improving karst hill circumstance, gradual vegetati
15、on restoration, build up corridors in appropriate region; enlarge the protection area and protection strength; enhance the Scotch cousin intercommunion of different groups.
