白河自然保护区川金丝猴栖息地景观格局分析

分析了2005~2007年四川省白河自然保护区川金丝猴栖息地的景观格局。结果表明：①白河自然保护区川金丝猴栖息地内共有斑块5 069.00个,斑块密度为2 595.00个/hm2,平均斑块面积为3.20 hm2,香农多样性指数为2.49,斑块丰富度为68.00,边界总长度为19 011 119.91 m,边界密度为97.34 m/km2,景观形状指数为35.19。②保护区内川金丝猴的栖息地质量下降,栖息地斑块破碎化现象较为严重,急需加强管护、加大投入。笔者建议通过在各自然保护区间建立生境走廊连接破碎栖息地;加强资源管护,严格审批旅游产品开发项目;加强对川金丝猴和其栖息地的科学研究投入和资金投入;采取改善当地社区环境的有效措施,缓解人员生活对保护区造成的压力;加强相关的宣传教育等手段,达到提高保护区内川金丝猴的栖息地质量、有效保护川金丝猴这一珍贵物种的目的。

Analysis on Landscape Pattern of Habitat of Sichuan Golden Monkey in Baihe Nature Reserve

The paper had analyzed landscape pattern of habitat of Sichuan golden monkey in Baihe Nature Reserve.The result showed: ① there were altogether 5 069.00 patches at habitat of Sichuan golden monkey in Baihe Nature Reserve,the patch density was 2 595 p/hm2,average patch area was 3.20 hm2,Shannon's diversity index was 2.49,patch richness was 68.00,total length of edge was 19 011 119.91 m,edge density was 97.34 m/km2,and landscape shape index was 35.19.② The quality of habitat of Sichuan golden monkey reduced,patches at the habitat were seriously fragmentized,and it urgently needed to enhance protection and increase investment.The paper suggested connecting fragmented habitats through establishing habitat corridor in nature reserve;strengthening resources protection and strictly examining development projects of tourist products;increasing scientific research and capital investment;adopting effective measures to ameliorate local community environment and relieving the pressure of nature reserve caused by people;intensifying relevant publicity and education,so as to improve quality of habitat of Sichuan golden monkey in the nature reserve and effectively protect this valuable species.
