摘要:

人类活动干扰是自然保护区监测的主要内容,目前遥感技术已成为保护区人类活动干扰信息获取的重要手段。随着不同时空分辨率遥感数据源的不断涌现,如何选取最适宜的遥感数据源进行干扰信息识别,是目前本领域需要解决的问题。本研究选取目前常用的资源卫星(Landsat-8)、高分卫星(GF-1等),针对保护区常见的6种人类活动干扰类型,选择2~30m多种影像进行了人类活动干扰信息识别,通过比较不同尺度数据的人类活动干扰信息提取结果,为自然保护区人类活动监测选择最适宜数据源提供支持。灵武白芨滩自然保护区的研究结果表明,较高分辨率的影像提取人类活动干扰的效果较好,内部均匀、分布集中、面积较大的人类活动干扰类型提取可以选取中、低分辨率影像为数据源,而分布离散、破碎、面积较小、细节要求较高的人类活动干扰类型提取需要选取高分辨率影像为数据源。研究成果可为保护区监测方案的制定提供决策依据。

Abstract:

Human activity information extraction is a primary part of nature reserve monitoring,and remote sensing technology has become a significant method to obtain human activity information. However,with the rapid development of remote sensing technology,various remote sensing data resources with multi-spectral and multi-spatial resolution are available. It cannot be ignored that data sources of different scales have significant effects on nature reserve monitoring. How to choose the most suitable data source for human activity information extraction and nature reserve monitoring is a key problem to be solved. In this study,we choose commonly used Landsat-8 satellite and GF-1 satellite’s imageries of resolution 2m panchromatic band,and resolution 8m/16m/30m multi-spectral bands,for six different kinds of human activity information extraction. By telling the difference among human activity information extracted from different scale data sources,we attempted to provide support for the selection of the most suitable data source in nature reserve monitoring. A case study is carried out for Lingwu Baijitan National Nature Reserve in Yinchuan, Ningxia,showing that imageries with higher resolution gets a better result of human activity extraction. Well-distributed,centralized and large area human activity landscapes could choose medium and low resolution imageries as the data source, while uneven distributed, fragmentized and small area human activity landscapes which has high requirements of details should choose high resolution imageries as data source. Research result is supposed to provide decision support for the establishment of nature reserve monitoring schemes in China.
