spatial distribution of population meaning in Chinese
人口地区分布
Examples
- The spd model is made by the ins titute of geographical sciences and natural resources research of chinese academy of sciences . it combines social economic factors , such as city and transportation foundational facilities , with nature factors , for example the digital elevation model ( dem ) and net primary productivity ( npp ) of plants to simulate the spatial distribution of population density of china by the advanced grid generation technology
中国模拟人口密度模型是由中国科学院地理科学与资源研究所首先提出的，这个模型试图利用先进的格网生成技术，将城市、交通基础设施等社会经济因子和陆地数字高程( dem ) 、陆地植被净第一性生产力( npp )等自然因子相结合，通过模型的反演，模拟某一时期的中国人口密度空间分布状况。 - The dissertation puts forward some viewpoints based on the domestic and overseas theoretic researchs and practices related to the locating supermarket . based on the analysis the indexes of the location of supermarket , we pay more attention to three application analytical indexes : spatial distribution of population numbers , traffic accessibility , competition between different firms , having realized the quantitative and visual analysis of the market area
本篇论文基于gis技术结合国内外关于超市选址的相关研究成果，对超级市场选址规划进行了有益的探索。论文通过对超级市场选址相关因素的分析研究，综合考虑了人口的空间分布、交通可达性、现有零售商业竞争态势等因素，实现了超市商圈分析的定量化。 - We got the spatial distribution map of population density by spatial interpolation , in which the population data are distributed on the grids . the results of the distribution of interpolated based on gis is closed to a real population distribution . the combination of the spatial interactive models and a shortest path algorithm for public transit network is analyzed by supermarket ' s accessibility based on pedestrianism and public transit . this methods may be used to investigate potential supermarket ' s locations . the quantitative analysis about the supermarket ' s market area is realized based on trade mode of lashmanan and hansen , which mainly includes spatial distribution of population , traffic accessibility and free competition between different firms
文中应用空间内插技术实现了人口数据空间分布化，将人口数据通过空间插值分布于研究区域内，使人口空间分布更接近实际；应用公交最短路径算法及空间相互作用模型实现了基于步行和公交出行的超市可达性，将交通对超市选址的影响定量化，方便了方案的比选；在综合考虑人口空间分布、超市交通可达性、现有零售商业竞争态势的基础上，基于拉、汉购物模式实现了超市商圈定量分析。
