Urban competitive pattern and its changes in China
Chinese Geographical Science - Tập 10 - Trang 105-112 - 2000
Wen-zhang Dou, Guo-ping Li, Ying-jin Gan, Li-ming Wang, Kai-zhong Yang
With the national economy’s transition from a planning one to a market one, the factors affecting regional economic pattern has changed greatly. In this paper we first construct an index system for evaluating competitiveness of Chinese cities based on modern competitive advantage theory. With principal component analysis and cluster analysis methods, we compare the factors affecting cities’ integr...... hiện toàn bộ
Comparative Analysis of Fractional Vegetation Cover Estimation Based on Multi-sensor Data in a Semi-arid Sandy Area
Chinese Geographical Science - Tập 29 - Trang 166-180 - 2018
Qiuyu Liu, Tinglong Zhang, Yizhe Li, Ying Li, Chongfeng Bu, Qingfeng Zhang
The estimation of fractional vegetation cover (FVC) is important for identifying and monitoring desertification, especially in arid and semiarid regions. By using regression and pixel dichotomy models, we present the comparison of Sentinel-2A (S2) multispectral instrument (MSI) and Landsat 8 (L8) operational land imager (OLI) data regarding the retrieval of FVC in a semi-arid sandy area (Mu Us San...... hiện toàn bộ
Extracting eco-hydrological information of inland wetland from L-band Synthetic Aperture Radar image in Honghe National Nature Reserve, Northeast China
Chinese Geographical Science - Tập 21 - Trang 241-248 - 2011
Yonghua Sun, Huili Gong, Xiaojuan Li, Ruiliang Pu, Shuang Li
Taking a typical inland wetland of Honghe National Nature Reserve (HNNR), Northeast China, as the study area, this paper studied the application of L-band Synthetic Aperture Radar (SAR) image in extracting eco-hydrological information of inland wetland. Landsat-5 TM and ALOS PALSAR HH backscatter images were first fused by using the wavelet-IHS method. Based on the fused image data, the classifica...... hiện toàn bộ
A study on rational location of the cotton production in China
Chinese Geographical Science - Tập 1 - Trang 129-140 - 1991
Zhuo Zhu
Cotton is the leading cash crop in China. The cotton sown area accounts for about 30per cent of the total sown area of all the various cash crops. It is the main material used in the textile industry in China. More than 95per cent of textile materials were cotton during the 1950s; and it still occupies 80per cent at present. There are some problems concerning rational location of cotton production...... hiện toàn bộ
Effects of environmental conditions and aboveground biomass on CO2 budget in Phragmites australis wetland of Jiaozhou Bay, China
Chinese Geographical Science - Tập 27 - Trang 539-551 - 2017
Manyu Gao, Fanlong Kong, Min Xi, Yue Li, Jihua Li
Estuarial saline wetlands have been recognized as a vital role in CO2 cycling. However, insufficient attention has been paid to estimating CO2 fluxes from estuarial saline wetlands. In this study, the static chamber-gas chromatography (GC) method was used to quantify CO2 budget of an estuarial saline reed (Phragmites australis) wetland in Jiaozhou Bay in Qingdao City of Shandong Province, China du...... hiện toàn bộ
Disasters and regional risks of debris flow in Zhaotong Prefecture, Yunnan Province, China
Chinese Geographical Science - - 1994
Xilin Liu
Zhaotong Prefecture has the area of 22,434km2, where there are more than 330 debris flow ravines, with the average spatial density of 14.7 spots per 1,000km2. According to the method of evaluation on the regional risk of debris flow, this study has come to the following conclusions: Qiaojia County-risk grade V; Yongshan, Yanjin, Ludian, Daguan, Weixin and Zhenxiong counties-risk grade III; Yiliang...... hiện toàn bộ
Landscape network approach to assess ecological impacts of road projects on biological conservation
Chinese Geographical Science - Tập 24 - Trang 5-14 - 2014
Shiliang Liu, Li Deng, Liding Chen, Junran Li, Shikui Dong, Haidi Zhao
Awareness of the adverse ecological effects of road and other large construction projects has resulted in a rapidly growing demand to quantitatively predict and evaluate the effects on gene flow among plants and animals in natural habitats. In this study, we evaluated the effects of different road construction scenarios on animal species movement by using the methods of ecological landscape connec...... hiện toàn bộ
Land-cover density-based approach to urban land use mapping using high-resolution imagery
Chinese Geographical Science - Tập 15 - Trang 162-167 - 2005
Xiu-ying Zhang, Xue-zhi Feng, Hui Deng
Nowadays, remote sensing imagery, especially with its high spatial resolution, has become an indispensable tool to provide timely up-gradation of urban land use and land cover information, which is a prerequisite for proper urban planning and management. The possible method described in the present paper to obtain urban land use types is based on the principle that land use can be derived from the...... hiện toàn bộ
Trend of precipitation variation in Hubei Province since the 1960S
Chinese Geographical Science - Tập 13 - Trang 322-327 - 2003
Zheng-hong Chen, Jun Qin
Through linear regression analysis to the trend of annual, seasonal and monthly precipitation of 72 meteorological stations in Hubei Province from 1961 to 1995, it is revealed that: 1) annual precipitation was increasing by 61.0mm/10a in the eastern part of Hubei (112°E as a dividing line) and decreasing by 34.9mm/10a in the western part; 2) precipitation in winter and summer (January, February, M...... hiện toàn bộ
