| 东江湖、水府庙水库和大通湖是湖南典型水库，以上述3个流域为研究对象，在土地利用类型遥感解译结果、社会经济统计数据以及水质监测数据的基础上，采用主成分分析和灰色关联度分析对研究区水质变化驱动力进行比较分析，为探究土地利用变化与社会经济发展对水库水质的影响。结果表明，东江湖流域的土地利用类型以林地为主，大通湖流域以耕地为主，水府庙水库流域内耕地和林地比例差异较为相似。土地利用类型和人类活动对3个水库的影响程度存在差异，东江湖水质变化的主要驱动因子为经济因素、林地及建设用地的面积比例。水府庙水库的水质变化主要驱动力为经济因素、建设及耕地面积比例的变化。大通湖水质变化的主要驱动力是经济因素、人口因素以及建设用地面积比例变化。湖泊受污染情况是大通湖 > 水府庙水库 > 东江湖。 |
| 英文摘要: |
| Land use changes and social economy development greatly influence the water quality of reservoirs. Dongjiang Lake, Shuifumiao Reservoir, and Datong Lake, which are three typical reservoirs in Hunan, were the subjects of this research. On the basis of remote sensing interpretation results of land use types, socioeconomic statistics, and water quality monitoring data, principal component analysis and grey relational analysis were used in this study to investigate the driving forces of water quality change in the study area, and comparative analysis was performed. The results showed that the main type of land use in the Dongjiang Lake basin was woodland, that in the Datong Lake basin was mainly cultivated land, and the proportions of cultivated land and woodland in the Shuifumiao Reservoir basin were not very different. The impact of land use types and human activities on the three reservoirs differed. The main driving factors for Dongjiang Lake water quality change were economic factors and the area ratios of forestland and construction land. The main driving forces for the water quality change of Shuifumiao Reservoir were the changes of economic factors, proportion of construction land, and cultivated land area. The major driving forces of Datong Lake water quality change were economic factors, demographic factors, and the proportion of the construction land area. The order of the reservoirs in terms of pollution level, from high to low, was Datong Lake > Shuifumiao Reservoir > Dongjiang Lake. |
