The Thornthwaite moisture index, an index of the supply of water （precipitation） in an area relative to the climatic demand for water （potential evapotranspiration）, was used to examine the spatial and temporal variation of drought and to verify the influence of environmental factors on the drought in the Hengduan Mountains, China. Results indicate that the Thornthwaite moisture index in the Hengduan Mountains had been increasing since 1960 with a rate of 0.1938/yr. Annual Thomthwaite moisture index in Hengduan Mountains was between -97.47 and 67.43 and the spatial heterogeneity was obvious in different seasons. Thomthwaite moisture index was high in the north and low in the south, and the monsoon rainfall had a significant impact on its spatial distribution. The tendency rate of Thomthwaite moisture index variation varied in different seasons, and the increasing trends in spring were greater than that in summer and autumn. However, the Thomthwaite moisture index decreased in winter. Thomthwaite moisture index increased greatly in the north and there was a small growth in the south of Hengduan Mountains. The increase of precipitation and decrease of evaporation lead to the increase of Thomthwaite moisture index. Thornthwaite moisture index has strong correlation with vegetation coverage. It can be seen that the correlation between Normalized Difference Vegetation Index （NDVI） and Thomthwaite moisture index was positive in spring and summer, but negative in autumn and winter. Correlation between Thornthwaite moisture index and relative soil relative moisture content was positive in spring, summer and autumn, but negative in winter. The typical mountainous terrain affect the distribu- tion of temperature, precipitation, wind speed and other meteorological factors in this region, and then affect the spatial distribution of Thomthwaite moisture index. The unique ridge-gorge terrain caused the continuity of water-heat distribution from the north to south, and the water-h

Chinese Geographical Science 2015年第2期25卷 250-262页

作者： LIU Hailong SHI Peiji tong huali ZHU Guofeng LIU Haimeng ZHANG Xuebin WEI Wei WANG Xinmin College of Geography and Environmental Science Northwest Normal University

This paper presents an integrated study of urban spatial expansion in the Hexi Corridor, Gansu Province, China based on TM, ETM remote sensing data in 1987, 1990, 1995, 2000, 2006 and 2011. The study explores the characteristics of urban spatial expansion and dynamic mechanism by using expansion speed index, expansion intensity index, compact index, fractal dimension, and extended flexibility index. We built the index system of influencing factors of urban spatial expansion by using the grey incidence model. The results showed that urban spatial expansion rate in the Hexi Corridor has been on the upward trend since 1987. Expansion intensity showed an obvious upward trend, however, the upward trend varied in different urban areas. In addition, the urban structure was loose relatively, but the urban compactness was more obvious. The urban spatial form tended to be simple, and the urban land use tended to become more intensive. Urban spatial expansion experienced several stages: padding internally, external expansion and padding internally. The main driving factors of urban spatial expansion are not the urban water resources and the oasis scale, but one or several factors such as economy, traffic, population, resource and national policy.

Ganzhou District is an oasis city in the Zhangye Municipality of Gansu Province, China. Based on multi-temporal TM and ETM satellite remote sensing data in 1985, 1996, 2000, and 2012, and by using corrected figures of land use status over the same periods, the spatial area of Ganzhou District since 1985 was extracted with statistical methods, and urban spatial expansion was measured by quantitative research methods. The characteristics of spatial expansion of Ganzhou District were analyzed by urban expansion rate, expansion intensity index, compactness, fractal dimension, and the city center shift method. The results showed that the built-up area of Ganzhou District increased by 3.46 times during 1985-2012. The expansion in 1985 1996 was slow, during 1996 2000 it was rapid, and during 2000-2012 it was at a high speed. This city mainly expanded to the northeast and northwest. Government decision making had a decisive influence on urban expansion. Initially the expansion was uniform, but later the local tfansportation, economy, resources, population, and national policies factors had an obvious influence on urban expansion.

河西走廊中部地区气候条件特殊,小循环过程独特复杂,因而应用降水等各种水体中的氢氧稳定同位素信息来明晰水循环特征,成为近年较为常用的方法.利用GNIP张掖站点大气降水稳定同位素资料和NCEP/NCAR再分析资料,通过研究张掖站11年大气降水的氢氧稳定同位素组成,建立了张掖局地大气降水线方程,结合西水、莺落峡、平川、正义峡4个辅助站点资料,分析了河西走廊中部地区氢氧稳定同位素的时间变化规律,并建立水汽输送模式.结果表明,除西水外,其余站点区域大气降水线方程的斜率与截距均低于全球和中国大气水线,说明河西走廊中部地区降水主要来源于大尺度水汽循环,局地蒸发较为强烈且降水过程中张掖站点的蒸发作用强于其他站点.河西走廊中部地区大气降水中δ18O与温度、水汽压之间呈现较为显著的正相关关系;在全年尺度下,降水量效应不明显;由于干旱区降水主要集中在气温较高的月份,在暖季,温度效应掩盖了降水量效应,使得降水量效应无法体现.对过量氘和水汽输送的研究表明,西风带的水汽输送为河西走廊中部地区提供了基本的水汽来源,西风带季节变化对其水汽输送通量散度和d值季节变化有直接的作用.从d值的变化来看,河西走廊中部具有明显的季节变化特征,暖季d值明显小于冷季,且呈现一种先降后升的变化趋势;从数值来看,暖季d值小于10‰的次数多于d值大于10‰的次数,冷季d值大于10‰的次数多于d值小于10‰的次数,说明冷季水汽在运行过程中受到地表水汽补给的作用明显.
