摘　　要：基于野外调查和地理信息系统技术,对四川省汶川县1974—2000年的土地利用变化进行了分析,并结合生境适宜性模型对野生动物生境适宜性进行了评价,分析了适宜生境变化的原因。结果表明:研究区1974—2000年土地利用变化明显,森林面积下降,而草地、灌木林地和农田增加;野生动物适宜生境减少,核心区面积减少且距离加大,不利于野生动物的保护。造成这一变化的主要原因是人口的增加和地区经济发展。因此,在经济发展的同时,应该加强野生动物的保护。Based on field investigation and geographic information system technology, the land use change in Wenchuan County of Sichuan Province from 1974 to 2000 was analyzed, and the habitat suitability for wild animals was evaluated by using habitat suitability model, with the change causes of suitable habitat analyzed. The results showed that from 1974 to 2000, the study area had an obvious land use change, with forest area decreased dramatically while the areas of grassland, shrub land, and farmland increased. The suitable habitat and its core area for wild animals decreased, and the distance between the core areas increased, which was not beneficial to the protection of wild animals. The increasing population and economy were the main causes for this change, and hence, the protection of wild-animal habitat should be strengthened with the development of economy.
