摘要:

利用无人机技术,以自然保护区实验区自然-人工复合生态系统为例,获取高分辨率遥感影像,并通过人工目视解译提取不同景观类型单元,分析研究复合生态系统景观格局及镶嵌结构特征。结果表明,乔木林、茶园、住宅区、灌木林是研究区主要景观单元,其次是疏林地、道路、工矿用地等人工表面以及耕地和沟渠等半自然景观。不同景观单元镶嵌结构和稳定性差异较大,其中乔木林稳定性最好,疏林地、库塘、果园、耕地、裸土地、工矿用地和其他人工表面等景观单元稳定性较好,灌木林、荒草地、茶园和住宅区等景观单元稳定性一般,沟渠、绿地和裸岩石砾等景观单元稳定性较差。

Abstract:

In this study,high-resolution images were obtained based on UAV technology,and landscape types were extracted through artificial visual interpretation.Then,landscape patterns and the mosaic structure of the natural-artificial ecosystem were analyzed.The results showed that timber forests,tea plantations,residential areas and shrub forests were the dominant landscape units,followed by sparse woods,roads,industrial land,farmland and ditches.The mosaic structure and stability of different landscape units varied significantly.According to stability index,timber forests were the most stable landscape units in the study area,followed by sparse woods,reservoirs and ponds,fruit orchards,farmland,bare land,industrial land and other artificial landscapes.The stability of shrub forest,grassland,tea plantation,residential areas and roads were at a moderate level,whereas ditches,green land and bare rocks were relatively unstable.The results may provide scientific basis for the protection and management of nature reserves.

Key words: high resolution image, nature reserve, complex ecosystem, landscape pattern, stability
