| 摘 要： | 提出了用于区域土地利用变化预测改进型的空间分析预测模型,以半干旱环境下典型生态脆弱区松嫩平原西部通榆县为例,用改进型空间分析测算模型分析了全县1992~2001年间土地盐碱化演化过程,并在此基础上预测全县未来29 a内土地盐碱化发展趋势。结果表明:(1)改进型空间分析测算模型可较准确预测区域未来某一时间点盐碱地数量与结构;(2)通榆县2030年以前将以非盐碱地快速盐碱化为主,其中低覆盖度草地和沼泽地是新增盐碱地主要来源;(3)随着气候变化和人类干预,全县土地盐碱化过程有一定可逆性,以轻、中度盐碱地向耕地、高覆盖草地、农村居民用地和城镇用地转化为主。

| Abstract: | The application of traditional spatial analysis model of land use is greatly restricted due to the complex logical structure itself and the lack of rules for restricting the maximum amount of each type of land use in future land use scenario.In this study,we brought forward an improved spatial analysis model for predicting the local land use change.Since land saline-alkailization is becoming one of the most serious geological-environmental disasters in the world and threatening the sustainable development i... |
