摘要
为缓解山地城市绿地生态破碎化,从自然、社会和文化三类影响因素进行绿地适宜性评价,结合绿地景观分割度指数(SPLIT)模型与双变量空间自相关模型,对新县绿地结构、布置和要素提出布局优化建议。适宜绿地建设区域共计约47.45 km^(2),占研究区总面积的58.31%,主要分布于建成区周边山体及附近;绿地景观分割度整体表现为北高南低、中低外高的空间分布特征,绿地布局体系尚未完善;高-高聚类主要分布于羚羊山、大石旁、虎脊山周边,应作为绿地建设重点区域;高-低聚类主要位于四面山、孟良山、羚羊山等,在绿地建设中应给予重点保护。
In order to alleviate the ecological fragmentation of green space in mountainous cities,the suitability of green space is evaluated from three influencing factors of nature,society and culture.Combined with green space landscape segmentation index(SPLIT)model and bivariate spatial autocorrelation model,suggestions on Layout Optimization of green space structure,layout and elements in Xinxian county are put forward.The suitable green space construction area is about 47.45 km^(2),accounting for 58.31%of the total area of the study area,which is mainly distributed in the mountains around the built-up area and nearby;The overall division degree of green space landscape shows the spatial distribution characteristics of high in the north,low in the south,low in the middle and high outside,and the green space layout system is not perfect;The high high aggregate is mainly distributed in the antelope mountain,beside Dashi mountain and around Huji mountain,which should be used as the key area of green space construction;High oligomeric species are mainly in Simian Mountain,Mengliang mountain,antelope mountain and other mountains,which should be protected in green space construction.
