摘要
在G IS、RS等软件的支持下,对福建省闽江流域、九龙江流域和晋江流域的MOD IS数据、气象数据和地形数据进行处理,建立三大流域的生态环境质量监测模型,研究分析福建三大流域生态环境质量的空间分布情况及动态变化趋势。研究结果表明:在人口聚集、经济发达、地势较为平坦和交通便利的区域生态环境质量较差,而在人口稀疏、经济欠发达的丘陵山区生态环境质量良好。福建三大流域中九龙江流域生态环境质量最好,晋江流域生态环境质量最差。随着时间的推进,三大流域的生态质量都在不同程度上出现缓和趋势,这是对流域生态环境保护工作所取得成绩的印证,也可为今后制定更加有效的生态环境质量保护措施和政策提供科学的参考依据。
In this study,all of the EOS-Terra/Aqua-MODIS data,topographical data and meteorological data throughout Minjiang River Basin,Jiulongjiang River Basin and Jinjiang River Basin in Fujian Province,were processed using geographical information system and remote sensing software,in order to analyze the spatial distribution and dynamic changing trends of the eco-environmental quality.The eco-environmental quality monitoring models based on remotely sensed data and ground observations in the three major river basins above mentioned were implemented.Research results indicated that： in the populous,well-developed,flat terrain and facilitated traffic regions eco-environmental quality was bad,while in sparsely populated,undeveloped regions eco-environmental quality was good.Among the three river basins,the eco-environmental quality in Jiulongjiang River Basin is the best,while the Jinjiang River Basin is the worst.Due to the implementation of some environmental protection measures,the eco-environmental quality of the three river basins have been improved in the recent decade.The analysis of the monitoring results of eco-environmental quality at regional level can provide meaningful grounds for the formulation of the eco-environmental regulations and policies.
