Abstract选取广西峰丛洼地的典型区域田东县为研究对象,基于遥感和GIS技术,结合气象站实测资料,应用联合国粮农组织(FAO)推荐的Penman-Monteith法和ArcGIS软件模拟研究区域生态需水的空间分布。利用Landsat 8数据解译出的土地利用数据,对研究区景观格局指数进行提取,分析生态需水与景观格局的相关性。结果表明:田东县年度植被生态需水定额为85.91~339.27 mm;北部和南部山区的植被生态需水定额相对较大,中部、西部和东南部区域的生态需水定额相对较小。植被生态需水定额与景观多样性、景观破碎度呈极显著负相关,相关系数分别为-0.198和-0.186;与景观连通性呈极显著正相关,相关系数为0.221。研究成果可为区域的景观格局优化管理和水资源优化配置提供依据。
