【摘要】：选取H市中心城区2009年和2010年发生的街头抢劫案件为研究对象,构建地理加权泊松回归GWPR模型,探讨不同性质土地利用对案件影响的空间差异性。研究表明,各类用地与街头抢劫的关系存在显著的空间异质性。其中,位于中心区外围的传统居住区和部分新建社区等居住用地对街头抢劫存在显著的负向影响;商业服务业设施用地对街头抢劫的影响总体上显著性不强,但与其中的商业设施点类型密切相关,独栋高层的商业综合体会使犯罪数量下降,而临街商铺形式的商业设施点则是犯罪高发区域;工业用地仅对老城区的街头抢劫产生正向影响;公园绿地总体上与街头抢劫案件呈负相关性,但城市开敞绿地多的地方案件数量也较多;交通设施用地与街头抢劫的关系则受到交通设施、道路等级、路网形态的影响。最后通过聚类分析发现,土地利用对案件影响的主导因素的空间分异模式与不同的城市功能分区有一定的对应关系,可以对每个功能分区根据其街头抢劫发生的主导因素制定相应的土地利用规划导则。
[Abstract]:Taking the cases of street robberies in H city center in 2009 and 2010 as the research object, this paper constructs a geo-weighted Poisson regression GWPR model to explore the spatial differences of the impact of different types of land use on the cases.The results show that there is significant spatial heterogeneity between land use and street robbery.Among them, the traditional residential areas and some newly built communities outside the central district have a significant negative impact on street robbery, while the commercial service facilities land has no significant impact on street robbery on the whole.However, it is closely related to the types of commercial facilities, the single high-rise commercial complex will reduce the number of crimes, while the commercial facilities in the form of street shops is a high incidence area of crime.Industrial land only had a positive impact on the street robbery in the old urban area, and the park green space had negative correlation with the street robbery cases, but the number of local cases with more open green space in the city was also more.The relationship between traffic facilities and street robberies is affected by traffic facilities, road grades and road network forms.Finally, through clustering analysis, it is found that the spatial differentiation model of the dominant factors of land use on the case has a certain corresponding relationship with different urban functional districts.According to the dominant factors of street robberies, the land use planning guidelines can be formulated for each functional district.
