摘要:
天然打草场作为半干旱牧区草地资源的重要组成部分,对维持草地生态系统的稳定与可持续发展具有重要意义。然而,长期以来,我国天然打草场空间分布数据匮乏,现有数据难以准确反映其现状,制约了草地资源的科学管理与保护。为解决这一问题,本研究基于多源遥感数据融合技术(Sentinel-2与Landsat-8影像),引入地形、光谱指数和纹理特征,采用面向对象分割和支持向量机(support vector machine, SVM)算法,对半干旱牧区天然打草场进行了高精度遥感提取。研究结果显示,2020-2022年间半干旱牧区天然打草场总面积为794.92万hm2,其中内蒙古北部牧区占比最大(81.19%),温性草原为主要打草类型(61.87%)。固定打草场和机动打草场面积分别为477.12万和317.80万hm2,占比分别为60.02%和39.98%,空间分布呈现明显区域差异。遥感提取总体精度达84.76%,Kappa系数为0.69,与地面调查数据一致性较高,其中内蒙古北部牧区精度最高(87.16%)。本研究填补了近10年来天然打草场空间分布数据的空白,为草地资源的科学管理、生态保护与可持续利用提供了可靠的数据支持。
