The Study On The Spatial-temporal Characteristics And Driving Force Of Construction Land Expansion In Dalian Economic And Technological Development Area

It is a universal concern to research on land use change and driving forces Current Landfor construction is an efficient land use patterns. Research on the construction land expansionis one of the key elements of land use change.It took Dalian economic and technological development area as the study area. Itexplores the main characteristics of temporal and spatial factors and driving forces of theconstruction land expansion. Economic and Technological Development Zone is a specificarea of need to adapt to the opening-up policy. To study the first state-level economic andtechnological development zone Dalian. It is reference of rational development to otherstate-level development zones in urban construction land.Based on the full definition of construction land and construction land expansion of theconcept and connotation, Using development zone in1990,2000,2010,2013Landsat remotesensing information resource base, using ENVI remote sensing image processing software forprofessional image processing, Including image correction, band synthesis, crop, It gets fourremote sensing images Dalian Development Area. It supervised classification for images, andconfident test for images. It got land use change chart. Using ArcGIS9.3to transferredland-use change information into diagram. Using MapInfo11extracted Space Zoneconstruction land Space distribution in1990,2000,2010,2013,it analysis on four imagesOverlay. It explores the time characteristics and spatial characteristics and factors drivingforces of the construction land changes since1990.First from time dimension,it choose quantitative indicators, such as the expandingspeed, the strength of expansion, the relevant elastic coefficient of expansion,and It study thechange of the development zone construction land from1990to2013. It is the initial stage ofDevelopment area construction land expansion from1990to2000.it is the high speeddevelopment period from2000to2010. The future of Development area construction landexpansion is still the expansion phase.it analyze variation characteristics from the change ofthe population, the increase of the gross value of industrial output, the growth of theregistered enterprises. then from the space dimension, it analysis the four periods of remotesensing image interpretation chart by spatial overlay, mainly using ArcMap9.3, Mapinfo11. It analysis further through making eight parties bitmap and radar map. Development areaconstruction land spatial expansion centered on the MaQiaozi streets. It explore in the eastand southeast around Dagushan peninsula.it research the space expansion driving forcecombining with development area administrative map, digital elevation simulation map,Traffic map,protect arable land distribution map, key enterprises Distribution map.Researching Development Area of construction changes provide a reasonable basis forfuture regional land use, It is to clear space for the expansion of construction land law, thepreparation of regional development plans. It provide a solid foundation based on, provide thebasis for future planning especially for the Dalian Development Area.
