Ecological Land-use Variety and Security Pattern Construction: A Case Study From Anqing, China

全体主题 > Urban Planning & Modeling

Ecological security is an overall reflection of the ecological integrity and health level of natural semi-natural ecosystems. The study obtained quantitative results of ecological land-use variety by using spatial transfer matrix, based on status maps of Anqing City in 2005 and 2017.We com-bined with the superposition analysis of ecological sensitivity and ecolog-ical disturbance evaluation to judge the strategic nodes and corridors of core protection type, including maintenance promotion type and poten-tial supplementary type in the study area. In addition, we introduced the model of minimum cumulative resistance to construct the ecological se-curity pattern, superimposing with the results of ecological land use. Ac-cording to the trend of change over the past decade, the study has the great significance to the ecological security pattern and we can effectively control and guide to take management strategy for security landscape.
