滇西北滇金丝猴栖息地景观格局分析及其破碎化评价

摘要

Habitat loss and fragmentation have become the major threat to biodiversity.It's very necessary to evaluate the landscape pattern and fragmentation of the species habitat.The landscape pattern and its fragmentation of habitat of Rhinopithecus bieti were evaluated in this paper.Results showed that the forest area, including the suitable habitat for Rhinopithecus bieti, accounts for 2/3 of the total study area was the dominant landscape type.The landscape pattern of study area has shown some degree of landscape fragmentation.The suitable habitat area was 308 212.44 hm2 which was 18.86％ of the total landscape area.Overall, the fragmentation degree was low.But it is essential to control the fragmentation and protect the habitat of Rhinopithecus bieti through habitat restoring and corridor rebuilding.%生境丧失及破碎化已成为生物多样性最主要的威胁之一,对物种栖息地的景观格局进行分析及对其破碎化进行评价显得十分必要.对滇金丝猴栖息地景观格局和破碎化进行分析评价,结果表明,包括滇金丝猴适宜生境在内的森林面积占整个研究区面积的2/3,是该地区的主导景观类型;研究区景观格局已表现出一定程度的景观破碎化.滇金丝猴适宜生境面积为308 212.44hm2,占整个研究区面积的18.86%.目前滇金丝猴适宜生境的破碎化程度较低,但仍需控制适宜生境已出现的景观破碎化,并通过生境恢复及廊道重建等措施加强对滇金丝猴的保护.
