利用本系统提供的空间分析、模型运算等分析工具，对2000 2001年北京城近郊区浅层地下水环境污染进行了如下评价分析工作： ( 1 )对地下水调查中检测出的各种有机污染物和无机污染物进行了空间插值分析，划定了超标区的分布范围； ( 2 )对2000年枯水期的浅层地下水综合环境质量进行了分析和评价； ( 3 )对1996 、 1999和2000年的综合水质评价图进行了对比分析，发现北京城近郊区浅层地下水环境综合质量逐年下降；预知未来几年内，浅层地下水环境质量不会有明显好转。 - As far as daily surface air mean temperature , rmsie is below 0 . 5ctc . as for daily surfac e air max and min temperature , the rmsie are respectively lower than 0 . 74 and 0 . 58 . ( 4 ) the model a takes into account the fact that temperature lapse rate changes according to such factors as topography , latitude , longitude and moisture transfer , etc . the effect of spatial interpolation that uses it is not noticeably ameliorated by contrast with using the model a . there remains a need for further study
其中，改进方案a与其它方法相比，效果较好，其me均在0 . 03以下，对于地面日平均气温场， rmsie均在0 . 50以下，对于表面大气日最高温度场， rmsie均在0 . 74以下，对于地面日最低气温场， rmsie均在0 . 58以下；在方案a的基础上，考虑温度直减率随经、纬度和地形以及水汽输送等因素变化的分区插值方案，与方案a比较，插值效果没有明显改善，因此还需要进一步的研究。 - During the course of the research , the criterions of the interpolation effect are mean error ( me ) , mean absolute error ( mae ) , root mean squared interpolation error ( rmse ) and the difference of mean square deviation between the measured and the estimated surface air temperature . the conclusions are as follows : ( 1 ) by contrasting the gaussian weighted model associated with the error modification with the gaussian weighted model , the error modification is proved to considerably ameliorate the precision of spatial interpolation ; ( 2 ) on the base of the gaussian weighted model , taking altitudinal effect into account can reflect the trend in which temperature changes according to the topographic altitude and may ameliorate the precision of spatial interpolation correspondingly and apparently , which indicates that topographical effect on the preciseness of spatial interpolation can not be disregarded in terms of the region with complicated topography ; ( 3 ) the map of daily surface air temperature distribution , using the modified gaussian weighted model a and b , can accurately reflect the temperature - changing - with - topographical - altitude trend . among them , the better is the model a , whose me is below 0 . 03 ?
在此过程中，采用平均误差( me ) ，平均绝对误差( mae ) ，插值平均误差平方的平方根( rootmeansquaredinterpolationerror ，简称rmsie ) ，插值前后测站要素值的均方差( meansquaredeviation ,简称msd )差值作为判定插值效果的标准，得出如下结论：通过高斯权重法与结合逐步订正的高斯权重法的对比，说明结合逐步订正方案的高斯权重法可大大提高地面日气温的插值精度；在高斯权重法中加入海拔影响项可以反映出温度随地形高度的变化趋势，同时也能较大地提高地面日气温的空间插值精度，说明在地形复杂的区域，地形影响在插值精度中是不可忽略的；对于高斯权重法的两种改进方案得到的地面日气温分布图都能很好地反映出表面大气气温随地形高度的变化趋势。 - 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
