摘要
在RS和GIS的支持下,应用景观生态学的理论和方法,使用ENVI4.8、ArcGIS10.0、Fragstats4.1等软件对TM遥感影像进行判读解译、数据处理与分析。通过采用景观空间格局指标(多样性指数、最大多样性指数、破碎化指数和优势度指数)定量分析和研究了2010年韩家园林场景观格局。研究结果表明:韩家园林场共有12种景观类型,其中草本沼泽和森林两种景观类型占主导优势,所占的面积比例最大,均超过40%。采矿迹地面积3094.83hm2,占总面积的1.36%。各景观类型所占比例差异较大。景观多样性指数和均匀度指数较低,景观为少数类型所控制,破碎度指数较大,景观受人为干扰程度较严重。因而,加强对韩家园地区湿地生态系统的保护与恢复刻不容缓。
Based on RS & GIS,using the theory & method of landscape ecology,applying software(ENVI4.8,ArcGIS10.0,Fragstats 4.1),TM remote sensing image were interpreted,data were processed &analyzed.Using the indexes of landscape spatial pattern(diversity index,the maximum diversity index,fragmentation index and dominance index),landscape patterns of Hanjiayuan Forest Farm were quantitatively analyzed.Result shows that:there were 12types of landscape;herbaceous swamp &forest are dominant,their proportion is more than 40%;mine land is 3 094.83hm2,accounting for 1.36% of the total area.The proportions of each landscape type have significant differences.The landscape diversity index and evenness index were lower,controlled by few types.Fragmentation index is bigger,human disturbance degree is serious.Therefore,strengthening the protection &restoration of wetland ecosystem in Hanjiayuan Forest Farm is vital.
