摘要：快速评估自然保护区的保护成效,对科学地制定管理决策具有重要意义.本文通过遥感解译进行景观分类和景观动态变化分析,使用保护性景观质量指数、人工景观干扰指数和景观保护成效综合指数等开展内蒙古阿鲁科尔沁国家级自然保护区2004—2014年的保护成效研究.结果表明:2004—2014年,该自然保护区内自然景观所占比例由92.2%增加到92.8%,天然草地和灌木林面积显著增加,但湖泊、河流快速减少;景观格局变化较大,主要景观类型面积转出率和转入率高,景观转类指数为0.33.自然保护区内各功能区的保护性景观及其占比均明显增加,保护性景观质量指数由24.37增长为25.36,景观质量得到提升.各功能区均存在不同程度的人工干扰,人工干扰景观面积增大;2004和2014年人工景观干扰指数分别为-0.79和-0.96,人工干扰强度变大.研究期间,内蒙古阿鲁科尔沁自然保护区的景观保护成效综合指数为3.5%,其景观保护成效达到"很好",野生动植物生境趋于好转.
To assess quickly the conservation efficacy of nature reserve is of make scientific management decisions. In this paper, the remote sensing image great significance to was first interpreted, in order to accomplish the landscape classification and analyze the landscape dynamic of Ar Horqin Nature Reserve, Inner Mongolia. And then we assessed the conservation efficacy of this nature re- serve during the 2004-2014 by using the quality index of protected landscape, interference index of anthropogenic landscape and conservation efficacy index, etc. The results showed that the proportion of natural landscapes in Ar Horqin Nature Reserve, Inner Mongolia increased from 92.2% to 92.8% during 2004-2014, with a significant increase in areas of natural grassland and shrub land, while the areas of lake and river reduced quickly. Meanwhile, the landscape pattern had significantly changed in this nature reserve. The proportions of areas transformed to and from other landscape types were particularly high, and the landscape tected landscapes in the nature reserve and its transformation index was 0.33. Moreover, the pro- various function zones increased obviously in area and proportion, with the quality index of protected landscapes of this nature reserve increased from24.37 in 2004 to 25.36 in 2014, indicating the quality of protected landscape improved. Nonethe- less, each function zone had different degrees of artificial interference in the nature reserve, and the artificial interfered landscapes increased distinctively. The interference index of anthropogenic land- scapes was -0.79 and -0.96 in 2004 and 2014 respectively, showing that artificial disturbance in- tensity was strengthened. On the whole, it was found that the conservation efficacy index of Ar Horqin Nature Reserve, Inner Mongolia was 3.5% during the study period, which achieved a ＂very good＂ landscape conservation efficacy, and wildlife habitat tended to be better.
