摘要

近几十年来，松嫩平原的生态环境严重恶化，荒漠化迅速发展，这与区域水土保持功能持续下降有关。本文应用生态学、经济学和生态环境科学等学科的有关理论，以TM／MODIS／DEM数据为基础，应用3S技术建立了松嫩平原水土保持价值的复合计算模型。计算表明，全区2001年水土保持总价值为662．63亿元，就单位面积的水土保持价值而言．林地最高，为173．59万元／km^2，草地次之，为70．42万元／km^2，耕地很低，为24．53万元／km^2，难利用地仅为2．89万元／km^2。水土保持价值分布的总趋势从东北向西南递减，从193．86万元／km^2降至18．87万元／km^2。研究指出，进行林地、草地建设是提高区域水土保持功能的关键，中、西部尤应加强水土保持工作。本文不仅解决了水土保持价值的量化问题，而且为绿色GDP的核算提供了基础数据。
