Analysis of Forest Ecological Patterns at Different Spatial Resolutions at County Scale:A Study of Youxian,Hunan Province
This article was based on the Morphological Spatial Pattern Analysis(MSPA)method,taking Youxian as an example,to construct a county-level forest ecological pattern through different spatial resolutions,screened forest ecologi-cal source areas,and analyzed landscape connectivity characteristics.The results show that Youxian has abundant forest resources,and the forest landscape is mainly composed of large patches with concentrated and contiguous distribution;Dif-ferent spatial resolutions have an impact on the landscape connectivity of the core area of the entire county.The smaller the spatial resolution,the more stringent and accurate the connectivity of the surrounding core area patches;The spatial resolution analysis of 10 m x 10 m is more suitable for the county scale.
