海峡西岸经济区景观格局特征研究

运用景观生态学的空间格局指数法,结合遥感和GIS技术,研究了海峡西岸经济区(海西区)2008年生态系统组成、景观格局特征以及与环境因子的关系。研究结果表明:(1)海西区主要由森林、草地、农田、水域、城镇和荒地构成,各景观类型高程分布差异显著。(2)森林是海西区的优势景观类型,呈规模化集中分布,草地和农田是海西区重要景观类型,斑块数量最多,分布零散;城镇和荒地的结构特征最差,表明其稳定性差,受人为干扰强烈。(3)水域的景观特征处于中间水平,斑块类型差异显著,但景观整体稳定性较强。(4)降水量、气温等自然因素是影响海西区景观格局的主要因素,人口密度和GDP等人为因素影响相对较弱。

Characteristics of Landscape Pattern in West Taiwan Straits Economic Zone

In order to provide the scientific basis for rational resources utilization and ecological environmental protection of West Taiwan Straits Economic Zone,the paper analyzed the ecosystem composition and the landscape pattern characteristics of the region in 2008using the spatial pattern index method of landscape ecology combined with remote sensing and GIS technologies.The results indicated:(1)West Taiwan Straits Economic Zone was mainly composed of forest,grassland,farmland,waters,wetland,urban land and some barren land with significant difference of elevations;(2)The predominant landscape is forest distributed concentratedly, while grassland and farmland are very important with a larger quantity of patches scattered in the whole area,and urban land and barren land have no good patterns,which are significantly influenced by human activities;(3)Water bodies are very stable with significant difference of shapes;(4)The natural factors such as the precipitation and air temperature are the main elements which impact the landscape patterns in the region while the human activities are less important.
