以徐州市区2000年和2006年土地利用基础数据为数据源,建立景观类型与土地利用类型的对应关系。将徐州市区景观划分成农业景观、园林绿地景观、居住景观、工业景观、商服公共设施景观、水体景观、交通景观和其他景观8种类型,获得2000,2006年徐州市区景观分类图。计算出景观格局指数,利用GIS的空间分析功能,对徐州市区景观格局及其变化特征进行分析。结果表明:在城市化驱动下,徐州市区农业景观主要向居住景观、工业景观转移,商服公共设施景观、居住景观和工业景观的相互转移频繁;农业景观在空间上逐渐分散,其余的景观类型呈现聚集的趋势;徐州市区呈现出景观异质性程度、斑块破碎化程度和王i王块复杂化程度均加强的景观格局变化趋势。
以徐州市區2000年和2006年土地利用基礎數據為數據源,建立景觀類型與土地利用類型的對應關繫。將徐州市區景觀劃分成農業景觀、園林綠地景觀、居住景觀、工業景觀、商服公共設施景觀、水體景觀、交通景觀和其他景觀8種類型,穫得2000,2006年徐州市區景觀分類圖。計算齣景觀格跼指數,利用GIS的空間分析功能,對徐州市區景觀格跼及其變化特徵進行分析。結果錶明:在城市化驅動下,徐州市區農業景觀主要嚮居住景觀、工業景觀轉移,商服公共設施景觀、居住景觀和工業景觀的相互轉移頻繁;農業景觀在空間上逐漸分散,其餘的景觀類型呈現聚集的趨勢;徐州市區呈現齣景觀異質性程度、斑塊破碎化程度和王i王塊複雜化程度均加彊的景觀格跼變化趨勢。

Based on the basic data of land use in Xuzhou City in 2000 and 2006, the correspondence between landscape types and land use types is established. The landscape classification maps are obtained in Xuzhou City in 2000 and 2006 by classifying the eight landscape types into agricultural landscape, garden green landscape, living landscape, industrial landscape, public facilities service provider landscape, water landscape, transportation land- scape and other landscape. By use of the spatial analysis function of GIS, the urban landscape pattern and its change feature are analyzed with the help of the landscape indices calculated. Driven by the urbanization, the agri- cultural landscape was mainly shifted to the living landscape and industrial landscape, and the metastasis among living landscape, industrial landscape, public facilities service provider landscape was frequent in Xuzhou City. The agricultural landscape gradually dispersed in space while the other seven types of landscapes have a trend of aggregation. The landscape pattern in Xuzhou City shows an enhanced trend of all the landscape heterogeneity degree, patch fragmentation degree and patch complexity degree.
