北京松山国家级自然保护区景观多样性遥感监测与评价

指出了北京松山国家级自然保护区是重要的森林型国家级自然保护区之一,主要保护天然油松林为主的暖温带森林生态系统。选用1991年TM及2009年北京一号小卫星影像,获取保护区景观类型信息,并通过对景观多样性评价指标的筛选、评价指标体系的构建以及评价方法的研究,从景观结构和景观干扰两方面进行景观多样性评价。本研究为我国自然保护区提供一种动态更新、长效实用的遥感监测思路,对自然保护区生物多样性保护具有重要参考意义。

Remote Sensing Monitoring and Evaluation of Landscape Diversity of Beijing Songshan National Nature Reserve

Beijing Songshan national nature reserve is one of the important forest--based national nature reserves in China, and it mainly protect natural pine forest of warm temperate forest ecosystems. This article uses Landsat TM images in 1991 and Beijing-- 1 satellite images in 2009 to obtain the information of protection types in Songshan reserve. And then it estimates landscape diversity from landscape structure and landscape disturbance through selecting and building evaluation index and studying evaluation methods. This research provides a dynamic and long-- term practical monitoring idea to the domestic nature reserves, and has important reference value to biodiversity protection.
