基于景观边界特征的土地利用布局

The Spatial Distribution of Land Use Based on Features of Landscape Boundaries

研究目的：分析景观边界特征的生态意义，用边界为参数构建土地利用格局的计算模型。研究方法：在景观生态学边缘效应的理论基础上，选择浙江省临安市青山湖街道为研究区域，用边界特征谱分析土地利用格局特征。研究结果：青山湖街道农用地与其他地类邻接程度均高于建设用地与未利用地，耕地、园地是当地人为活动较频繁的区域。研究结论：基于边界特征的土地利用布局定量研究，可为土地利用规划布局方案选择提供简便易行的评定方法。

The purpose of the paper is to develop a land-use spatial distribution model incorporated with the boundary parameter and the ecological effects of the different landscape boundaries. The method used was to apply the spectral analysis to a case study in the Qiangshanhu Town of Linan City in Zhejiang Province based on the marginal effect theory in landscape ecology. The results indicated that the boundary linkage effect of agricultural land use was higher than that of the construction land and unused land. Therefore it can be argued that the cultivated land for paddy and vegetable were the area of the most frequent human activities. It was concluded that the model developed in the paper could be used as a simple and easily-implemented method for assessing the spatial distribution of land uses in land use planning design.
