Abstract:

土地盐渍化是影响区域生态环境质量和农业生产安全的重要因素,掌握其区域分布规律对盐渍化的预防和治理具有重要意义。基于ALOS影像和实地调查、土壤样品分析数据建立内蒙古杭锦后旗农用地盐渍化等级划分标准和遥感解译标志,分析了不同地物在不同波段的光谱特征,获得杭锦后旗土地盐渍化等级分类图。结果表明,杭锦后旗农用地盐渍化严重,中度以上盐渍化农用地占土地总面积的15.76%,占农用地总面积的25.68%;重度以上盐渍化农用地占土地总面积的3.28%,占农用地总面积的5.33%。研究区微度和轻度盐渍化农用地分布最广,中度盐渍化农用地分布比较分散,重度盐渍化农用地和盐土则主要沿灌渠和海子边缘分布,由西北向东南重度以上盐渍化土地比例有增加的趋势。
