Extended Research And Analysis Of The GIS And RS Based On City Space

As a coastal city--Qingdao, its position is important impact on our province and even thewhole country. Because many articles on the central area of Qingdao, but the city has greatrelationship with the surrounding area also, should go to study in Qingdao city from a deeper,broader perspective, so as to promote the overall development of the city, this paper takesQingdao city the area as the study area, including the town center six according to the cityzoning district, the new, Jiaonan and Huangdao united in one area--Huangdao area, includingfour county-level cities around them. In this paper, through the University of Marylandwebsite database is a collection of TM remote sensing data in Figure2002,2006,2010,2013and four year of October each year for data extraction, obtained the development and use ofland type, use regression model, to study the relationship between land use and city spaceexpansion, a comparative analysis is carried out to extract entity city space four year graphics,this paper also collect some information about the city in2020the overall planning, based onmany research summary, summarizes the characteristics of city spatial expansion of the past,to explore the future direction of city expansion, this paper put forward some suggestions ofpersonal extension of city space.(1) by comparing the obtained2002-2013years of data, Qingdao City area of the entity isa growing process. Among the various types of land, cultivated land, forest land, water area ofthree types of land use is a declining process, only the construction land continued to increase.In other words, expansion of Qingdao city in recent years in the process of city space, mainlyin the city construction land occupation of agricultural land (cultivated land) and forest land inthe process of. At the same time, the process of the research, the research method of circularratio and compactness, city space entity extraction on the use of technology was studied,using fractal dimension to analyze the morphology, found the city spatial expansion ofdisorder and blindness in the process of. Therefore, in the future city development process,Qingdao City Hall should urge the relevant departments to do all kinds of balance control atthe same time, focus on the city of healthy development, eliminate blind and disorderlydevelopment.(2) in the next few years, the reasonable development and utilization will be the focus ofthe work of the government of Qingdao downtown city space.2020planning new development land, residential land and industrial land proportion is still larger, more scattereddistribution of residential land, industrial land mainly concentrated in four cities around,therefore, in the development process, attention should be paid to the monitoring ofresidential land expansion, to prevent the blind expansion, at the same time, attention shouldbe paid to control the speed and scale of industrial expansion, more important is, in thegrowing period of environmental damage, Qingdao city should be in the prevention andcontrol of pollution aspect.(3) Qingdao city spatial expansion and most of the other city, there is change of landbetween the city space expansion, mainly in the city construction land occupation ofcultivated land, woodland phenomenon, in addition, as the waters of many city, in2008afterthe reclamation is an active period, change a lot of water. Therefore, in the future citydevelopment process, focus is to implement the policy of country, ecological environmentprotection, development and utilization of resources in a reasonable and orderly.
