A Study To Zhucheng City's Expand

Zhucheng city locates the southeast of Shandong peninsula,whose history is long, and it is a new developing industry cityalong the coast , with development of the economic, the city'spopulation, space to distribute and the land use scalecontinuously take place to changes, which cause the populationand area expand obviously, which caused a series of problem.Such as the pollution density in center of the city is over bigbecause of service and third industry's concentrate, thetransportation blocks up, the function to deal with the affairsarising suddenly is lower, the industry occupy too much landand its distribute is not reasonable and wastes plenty ofland ,the environment problem turn worse, and the cityecosystem weak obviously, fundamental facilities lay behind,the area of woodland, vegetables and crop increase continually,the type of ecological becomes simple, the biotic resources isinjured seriously etc. Many problem caused by the city's fastdevelopment in Zhucheng deserve to study. The study to city's expand is an important contents ingeography, city planning...etc. the study make use of themethods that quantitative analysis and the qualitativeanalysis that combine together to study the variety process incity scale in the space, land use, property layout, thepopulation's moving etc, announce the correlation andregulation in city expand which lies on the factor in naturegeography, the level of economy development, a suggestion aboutharmonious relationship between human and environment issupported finally.The contents of the text: First, the construction of the land usein Zhucheng is divided into seven types: enterprise land, living land,public facilities land, vacant land, useless land, water land and theothers. Then make use of CAD(computer assist design)and GIS(geographyinformation system) to gain information at that time from topographic map ,aviation shoot image and remote sense image, analogize the time-spaceevolution of the city land-use ,then join together the society and economycovariance, make use of the gray connection analyze method to analysesquantitatively and qualitatively the moved factor during city expand,according to the gray estimate model to estimate the city in the future,finally bring upped the possibility advices to expanding of future city.Technique characteristics:(1) Investigated the methodthat how to gain information of land use by make use of the CADfaced GIS, the accuracy of the digitized result that proved good.(2) Discuss and solute these theories: how to gain the date ofthe digital elevation model, the theories adopting the kind,surface set upping the mold, how to calculate and proceedirregular triangle net, put worth to digital elevation model.(3)under the GIS's support, city space's distribute that beconjectured and showed, analyses the related grounded.(4)Analyzed and predicted the city's expand, the result ofaccuracy proved Satisfy.
