摘要
利用遥感、GIS和GPS地面详查等手段对黄土丘陵区燕沟流域景观进行研究,对流域内油田开发土地占用及其与景观破碎化之间的关系进行分析。结果表明:油田开发占用土地面积相对较少,但主要以优质农业生产和生态建设用地为主;油田开发前后土地利用变化表现为林草地和耕地面积减少,交通、居民点及工矿用地和水域面积迅速增加;3个研究分区景观总体和景观类型的破碎化程度均为油田开发区(油区)>全流域>非油区,2003—2006年3年间,油区各景观类型破碎化指数显著增加,显示出油区景观破碎化程度增大;油田道路建设是油区景观破碎化的主要驱动力。
In this paper, the landscape pattern of Yangou catchment in the Hilly-gully region of Loess Plateau was studied with RS, GIS and field investigation with GPS, and that land use by oil exploitation and the resulting landscape fragmentation were analyzed. It was displayed that the oil field occupied rather a little land, but it was mainly high quality land for agricultural production and eco-environmental restoration. The area of forestland, grassland and farmland decreased, while the area of traffic, water, residential and industrial lands increased greatly in the oil field region of the catchment after three years of oil exploitation from 2003 to 2006. The fragmentation indexes of landscape of the three study areas were in descending order as follows： oil field region, whole catchments and non-oil field region. And those indexes of landscape elements in the oil field region were also increased significantly after oil exploitation. The results also revealed that roads had a great impact on landscape fragmentation in the oil field areas.
