摘要:
为深入刻画烟台市海岸带土地利用空间结构特征，以烟台市农村土地利用详查成果数据为基础，利用分形理论和GIS空间分析方法，选取边界维数、计盒维数、信息维数和半径维数4个特征参数，对海岸带各土地利用类型的斑块复杂性、空间占比、空间分布的均衡性和向海聚集性进行了分析。研究结果表明：受人为干扰强的建设用地、耕地、园地和其他土地边缘相对比较规则且简单，而自然性较强的草地、林地、水域及水利设施和滩涂在人类活动干扰下正处于运动变化的随机状态，斑块边缘相对复杂；海岸带土地利用是以建设用地和耕地为主，其他用地类型为斑块镶嵌体的景观结构模式；土地利用空间分布的均衡性与空间占据能力表现出一定的正相关性；各用地类型斑块密度在海陆梯度上均呈现衰减的趋势，向海聚集程度的强弱，使得土地利用形态在海陆梯度上呈现似圈层状空间分异规律。分形理论的引入，为定量分析海岸带土地利用的合理性和科学性提供了新的研究方法。
Abstract:
In order to further reveal spatial structure characteristics of land use in the sea coastal zone of Yantai City, based on the data of Yantai detailed rural land surveys, we used fractal theory and GIS spatial analysis method to analyze the patch complexity， spatial occupation，uniformity of spatial distribution and seaward agglomeration for each land use type through calculating the four parameters: boundary dimension, box-counting dimension, information dimension and radius dimension. The results indicate that the land uses under intensive human disturbance, such as construction land，cultivated land and garden plot, are comparatively regular and simple, while natural land uses, such as grassland，forestland，water body and water conservancy facilities, are more complicated and in the random state of motion and change. The model of land use is a landscape structure one with construction land and cultivated land as the dominant types and the other land use types as patches mosaic. There is the positive correlation between spatial occupation and uniformity of spatial distribution. On the sea-land gradient, patch desity of land use shows a descent tendency and the land use spatial patter presents a similar ring structure with different seaward agglomeration degrees. Fractal theory can provide a new research method for quantative analysis of the reasonability and scientilicality of land use in the sea coastal zone.
