【摘要】：合理优化乡村聚落空间格局对区域生态环境保护具有重要意义。该文以山丘生态保护区山东省泗水县为例,运用最近邻点统计、空间关联测度模型、空间韵律测度等方法分析泗水县乡村聚落空间分异特征,并从生态保护与建设的视角,运用最小累积阻力模型从森林、水体2个方面构建生态保护格局,探讨泗水县乡村聚落格局优化方向。结果表明:泗水县乡村聚落空间集聚态势显著,平均密度在1.6~4个/km2范围内,呈现出的"南北密,中间疏"的空间分异特征;聚落规模以小型聚落居多,斑块数量占总数的45.43%,存在低值集聚的冷点区,表现为"中部大,南北小"的分布态势;乡村聚落斑块形状较为复杂,连续性差,破碎化明显;聚落主要分布在高程73~250 m、坡度0~5?以及距河流600 m范围内。通过构建生态保护格局并根据乡村聚落对森林、水体的影响将其划分为重点整治型、限制扩张型、适度建设型和优先发展型4种格局优化类型,该研究结果可为生态保护与建设背景下区域乡村聚落的规划发展提供依据。
[Abstract]:It is of great significance to optimize the spatial pattern of rural settlements for the protection of regional ecological environment. Taking Sishui County, Shandong Province, as an example, this paper analyzes the spatial differentiation characteristics of rural settlements in Sishui County by means of nearest neighbor statistics, spatial correlation measure model and spatial prosody measure, and from the perspective of ecological protection and construction. The minimum cumulative resistance model was used to construct the ecological protection pattern from two aspects of forest and water body, and the optimization direction of rural settlement pattern in Sishui County was discussed. The results show that the spatial agglomeration of rural settlements in Sishui County is significant, the average density is in the range of 1.6 ~ 4 / km ~ 2, showing the spatial differentiation characteristics of "north and south dense, middle sparse", and the scale of settlement is mostly small settlement, the average density is 1.6 ~ 4 / km ~ 2, and the average density is 1.6 ~ 4 / km ~ 2. The number of patches accounts for 45.43% of the total, and there is a low value concentrated cold spot area, which is characterized by "the middle part is large, the north and south are small", the shape of rural settlements is more complex, the continuity is poor, and the fragmentation is obvious, and the settlement is mainly distributed in the elevation of 73 ~ 250 m, with a slope of 0 ~ 5? And within 600 m of the river. By constructing ecological protection pattern and dividing it into four types according to the influence of rural settlements on forest and water body, it can be divided into four types: key regulation type, limited expansion type, moderate construction type and priority development type. The results can provide basis for the planning and development of regional rural settlements under the background of ecological protection and construction.
