- 摘要:
- 景观生态综合评价对区域区划有重要的意义，以黑龙江帽儿山为例，以2006年林相分布图、Landsat TM遥感数据、地形图、二类调查数据和其他数据材料为数据源，以GIS为技术手段，选取景观类型破碎度、景观形状指数、土壤侵蚀类型、地形因素（坡度）、土地利用类型、植被盖度指数与气象因子（年降水量）7个指标对研究区域进行景观生态综合评价，在此基础上进行景观生态区划。研究结果表明：（1）全面分析景观生态综合评价指数并进行分级处理和景观区划，分为Ⅰ、Ⅱ、Ⅲ、Ⅳ和Ⅴ级区域，分别代表好、较好、中、较差和差5个级别；（2）不同景观生态综合评价区域面积所占比例的排列顺序为：Ⅱ>Ⅲ>Ⅳ>Ⅰ>Ⅴ，Ⅱ级区域所占的比例最大，在整个研究区域中占据绝对的优势，区域景观生态质量属于较好水平；（3）景观生态质量垂直分异明显，第一、二高程带的景观质量较好，Ⅱ级区域在一、二高程带所占比例较大，在第二高程带达到最大，第三、四和五高程带的景观质量较差。可见基于DEM模型和景观生态综合评价揭示景观生态质量的空间特征。
- Abstract:
- Landscape ecology evaluation had important significance to regionalization.Maorshan farmland of Heilongjiang Province was taken as example,based on GIS techniques,the data of forest distribution map of 2006,Landsat TM images,topographic map,the second survey data and others were used in this paper.Seven indices such as landscape type,landscape shape index,soil erosion type,terrain factor (slope),land use type,vegetation cover index and weather factor (rainfall) were selected in this model.On this basis,the integrated landscape ecology evaluation was made in the study area,according to the results of integrated landscape ecology evaluation,the landscape ecology planning was finished.The results showed that: the index of integrated landscape ecology was analyzed and reclassified,the landscape ecology planning was made,there were Ⅰ,Ⅱ,Ⅲ,Ⅳ and Ⅴ grade regions,which mean better,good,medium,bad and worse; the area proportion sequence of different integrated landscape ecology evaluation region was Ⅱ>Ⅲ>Ⅳ>Ⅰ>Ⅴ,the area proportion of Ⅱgrade region was the largest of the study area,the region eco-environment quality was good.The vertical differences of eco-environment quality were evident,the region eco-environment quality of first and second elevation level was good,the area proportion of Ⅱ grade region was lager of this region,which was largest in second elevation level,the region eco-environment quality of the third,fourth and fifth elevation level was bad.It was very clear that the result of DEM combined to integrated landscape ecology evaluation could reveal the spatial distribution characteristics of landscape ecological quality.
