不同地形条件下的村镇形态特征识别方法研究

Study on Identification Method of Morphological Characteristics for Villages under Different Terrain Conditions

以平原村镇香河县、山地村镇密云县和水乡村镇昆山市为例,研究了其村镇形态特征,建立了基于面积和周长的形状指数模型,并用变异系数对该模型进行了比较与验证。结果表明:此模型同时考虑了面积和周长两个要素,更加敏感,能够更好地区分不同类型的村镇。

Take Xianghe county of plain, Miyun county of mountainous area and Kunshan city of aqueous area as examples. The morphological characteristics of villages were studied. The shape index model based on area and perimeter was established, and the model was evaluated and verified based on coefficient of variation. The results showed that this model took both the area factor and the perimeter factor into consideration, and therefore it was more sensitive, and could distinguish different types of villages better.
