摘　　要：在生态环境领域,流域通常指由分水岭为界,由汇水区为单元组成的一种独立区域,是水环境治理、水生态修复、水资源调配、水安全保障的最优科学管控单位。通过运用各种空间插值方法,开展流域区域内水质、土壤质量、气候、水文水资源等生态环境因子的时空分布与变化研究,具有巨大的应用需求和良好的发展前景。本文基于已有的文献,对空间插值中的反距离权重法、样条函数法、自然邻域法、克里金法和趋势面法等5种常见空间插值方法进行概述和对比分析,并总结了各空间插值法对流域中不同生态环境因子的适应性。结果表明,各种插值方法都有一定的优点和缺点,不存在适用于任何流域状态的空间插值方法。但对于不同的应用对象、不同的数据分布情况、不同的地形地貌和不同时空尺度,各插值法的精度、稳定性等结果存在相对优劣。In the field of ecological environment,a basin usually refers to an independent area bounded by watershed and composed of catchment areas as units.It is the best scientific control unit for water environment management,water ecological restoration,water resource allocation,and water security.Through using various spatial interpolation methods to conduct research on the spatial and temporal distribution and change of ecological environmental factors such as water quality,soil quality,climate,hydrology and water resources in a basin area has great application demand and good development prospects.Based on the existing literature,this paper summarizes and compares five common spatial interpolation methods in spatial interpolation,including inverse distance weighting method,spline function method,natural neighborhood method,Kriging method,and trend surface method,and the adaptability of various spatial interpolation methods to different ecological and environmental factors in basin was summarized.The results show that all interpolation methods have certain advantages and disadvantages,and there is no spatial interpolation method applicable to any basin state.However,for different application objects,different data distribution,different landforms and different space-time scales,the accuracy and stability of each interpolation method have relative advantages and disadvantages.
