Based on the data of urban land use obtained by remote sensing interpretation from aero images in 1986 and 2004, the spatial structure of Jinan is studied in this paper with the method of geographic information system (GIS). According to the proportion of land for residence, industry and commerce, the urban district can be distinguished into three rings. Compared with the traditional theory of the ring structure in Western coun- tries, they have many distinctive characteristics. The main func- tions of the inner ring include residence, business and banking, but the proportion of residential land (more than 50%) is considerably higher than that of the cities in Western countries. The land proportion for residence and industry in the intermediate ring is equal on the whole. The main land of the outside ring is for industrial use. From 1986 to 2004, great changes have taken place on the land proportion of different types of use. In the inner ring, the land for residential and industrial use has shrunk much while the land for commercial use has increased. In the intermediate ring, the changes of the three types of land use were not very much and the temporal variation was relatively stable. On the contrary, the structure in the outside ring varies acutely. Though most of it is also for industrial use, the proportion of residential land has in- creased much. The three rings can also be divided into several sectors respectively, according to the function of land use clusters. New trends and mechanisms of the changes of land use impacting the urban structure were proposed in the end of the paper.

By integrating forest inventory data with remotely sensed data, new data layers for factors that affect forest fire potentials were generated for Baihe Forestry Bureau in Jilin Province of china. The principle component analysis was used to sort out the relationships between forest fire potentials and environmental factors. The classifications of these factors were performed with GIS, generating three maps: a fuel-based fire risk map, a topography-based fire risk map, and an anthropogenic-factor fire risk map. These three maps were then synthesized to generate the final fire risk map. The linear regression method was used to analyze the relationship between an area-weighted value of forest fire risks and the frequency of historical forest fires at each forest farm. The results showed that the most important factor contributing to forest fire ignition was topography, followed by anthropogenic factors.

A contrast of two typical LUCC processes and their driving forces in oases of arid areas: A case study of Sangong River Watershed at the northern foot of Tianshan Mountains

引用

Science china Earth Sciences 2007年第S1期 65-75页

作者： TANG FaShu1,2, CHEN Xi1, LUO GePing1, LIN Qing1,2 & LIU HaiLong1,2 1 Xinjiang institute of Ecology and Geography, Chinese Academy of Sciences, ürümqi 830011, china 2 Graduate university of Chinese Academy of Sciences, beijing 100049, china

Aerial photographs taken in 1978 and 1987, Landsat TM images in 1998 as well as soil, hydrology and socio-economic data for the oases in Sangong River Watershed were processed by remote sensing (RS) and geographic information system (GIS). There are two typical agricultural land uses in oases, Farm-based Land Use with large-scale intensified agricultural activities (FLU) and Household Respon-sibility-based Land Use with small-scale activities (HRLU). The Index Model of Land Use/Land Cover Change (LUCC), Weighted Index Sum (WIS) and logistic stepwise regression model were estab-lished to contrast the two typical LUCC processes and their driving forces. The land use patterns were dominated by cropland and grassland for the entire region, and cropland, residential and industrial land were increasing stably. In the HRLU areas, woodland and grassland declined dramatically, but in the FLU areas, grassland decreased only by 12.0%, whereas woodland increased by 13.7%. LUCC was stronger in the earlier stage (1978-1987) than in the later stage (1987-1998) for the entire region. LUCC was more intense in the HRLU areas than in the FLU areas during the entire period (1978-1998). Policy was a key factor in the land use change, and water resources were a precondition in land use. Under the control of policy and water resources, the main human driving factors included population and economy, and the main natural restrictions were soil fertility and groundwater depth. Human driving factors controlled the land change in the HRLU areas, but natural restriction factors dominated in the FLU areas. In the mean time, intensification of LUCC in the region had some spatiotemporal implications with a fluctuation of impact factors.

利用地理信息系统技术对不同坡度等级情况下的土壤侵蚀特征进行了分析。首先,利用地理信息系统软件从DEM数据中产生坡度数据,将其分级为6个等级。然后与土壤侵蚀数据集进行叠加统计分析,从而得到不同坡度等级情况下的土壤侵蚀特征。本文研究表明:(1)坡度等级从2～5级,轻度以上水蚀所占百分比逐渐降低。(2)在所有坡度等级上,轻度以上风蚀所占百分比均在86.8%以上。在第2坡度等级上,风蚀综合指数最高,而在第5坡度等级上,风蚀综合指数最低。(3)冻融侵蚀综合指数的最高值出现在第3坡度等级上,其最低值出现在第6坡度等级上。(4)在各个坡度等级上,均以水蚀为主,均在46%以上,其最高值为73.8%,出现在第4坡度级上。此外,在第1坡度级上,风蚀占次优势,而在第2～6坡度等级上,冻融占次优势。(5)坡度等级在1,2和3级上,其轻度侵蚀所占百分比和土壤侵蚀综合指数均相对较高,而在坡度等级4,5和6级上,轻度侵蚀所占百分比和土壤侵蚀综合指数均相对较低。这主要是由于在坡度等级较低的情况下,人为活动比较多,土地利用程度较高,对植被和土壤的破坏较大,从而导致这种反常现象。
