3s-based Wenshang County Land Use Dynamic Change Research

The Wenshang county of Shandong Province was taken as an example in the presentation to study landuse temporal-spatial change and the reasons resulting in this change. Based on the foundation of analysis of the domestic and international landuse/landcover change (LUCC) study, Remote Sensing (RS) and GIS were used as support technique to obtain the background data of landuse in this text. Society statistic information also was collected for study the space-time dynamic change pattern and this change would bring on what ecosystem and environment domino effect.This paper is composed of three parts. In the first part, Wenshang SPOT imaging in 2004 was analyzed in order to get the foundation data of landuse. The results showed that:(1) The land used for agriculture was the main landuse pattern form in Wenshang. The proportion of cultivated land: garden plot: woodland: water area is 61.5: 3:5.5: 5.9.(2) There was district difference on Land use structures and the space differences of garden plot, woodland are obvious comparatively other landuse pattern forms.(3) There were mainly three forms of distribution existed for landuse pattern in Wenshang, which are in the cultivated land continuous distribution way, the band structure formed in forest land and that in the scattered distribution way with the inhabitant and independent factory and mining.Landuse changes close 10 years were gained by overlay the data gotten before and landuse investigate data in Wenshang in 1996 using GIS software (Arcview3.2). GIS was used for data analysis by special interpolation based on the groundwater monitoring data from 1995 to 2004. Spatial maps of groundwater table and detailed groundwater resource changes at the study area were gotten. The relationship between landuse and groundwater table was analyzed to study the pertinence of landuse and entironment. The results are as fellows:(1) In recent 9 years, the quantity of cultivated land, water area and virgin land has been gradually decreased. But the quantity of garden plot, woodland rising sharply and the change rate were larger than average level and annual transform ratio reach 25%. The quantity of cultivated land was increased but the increasing slope was small.
