| 摘 要： | 湖(库)滨带是一种典型的水陆生态交错区,具有重要的生态、经济和社会价值,而土地利用对其生态环境具有重要影响。以平顶山市白龟山水库库滨带为例,从土地利用类型的角度,构建了土地利用生态环境影响的多层次综合评价指标体系,以遥感手段获取土地利用类型相关信息,采用专家打分法对评价指标进行量化分级,采用层次分析法确定各层次因子权重。评价结果表明,土地利用对白龟山水库库滨带生态环境产生了明显的负面影响,不同分区土地利用生态环境影响程度具有显著差别,影响大小次序为:分区1分区2分区3,分别属于较大退化影响、中度退化影响和轻微退化影响;影响较大的土地利用类型主要有城市建设用地、果园菜地、耕地、林草地以及工矿用地等。

| Abstract: | As a kind of typical aquatic-terrestrial ecotone,riparian zone has very important ecological,economic,and social values,whereas landuse has a major impact on ecological environment of riparian zone.Exemplified with buffer zone around Baiguishan Reservoir in Pingdingshan City,an evaluation index system indicating the impacts of landuse on ecological environment was formed in view of landuse type.Remote sensing techniques were adopted to acquire landuse information,expert marking method was used for index quantification,and AHP method was adopted for index weight determination.Evaluation results show that landuse has a moderate negative influence on ecological environment of buffer zone around Baiguishan Reservoir.Impacts of landuse on ecological environment in different divisions of buffer zone are different.The order of the three divisions is No.1No.2No.3,among which division No.1 has a greater impact,division No.2 has a moderate impact,and division No.3 has a light impact.The landuse types having greater impacts on ecological environment in the buffer zone are the urban construction land,orchard and vegetable land,and forest and grassland,as well as industrial and mining lands. |
