Assessment model of atmosphere transmitting influence on high-resolution airborne SAR stereo positioning

Zhaoqing Zheng, Lei Pang, Xuexing Chen

Chinese Geographical Science > 2008 > 18 > 4 > 369-373

The influence derived from atmosphere transmitting of radar wave, in the application of high-resolution airborne Synthetic Aperture Radar (SAR) stereo positioning, may produce some phase errors, and eventually be introduced into positioning model. This paper described the principle of airborne SAR stereo positioning and the error sources of stereo positioning accuracy that arose from atmosphere transmitting,...

Measurement and spatial distribution of urban agglomeration industrial compactness in China

Weifeng Qi, Chuanglin Fang, Jitao Song

Chinese Geographical Science > 2008 > 18 > 4 > 291-299

Urban agglomeration (UA) compactness means spatial concentration degree of physical entities, such as cities (towns), industries, resources, funds, traffic and technologies, whose concentration is formed according to specified economic and technologic association in the process of UA formation and development. The UA industrial compactness means the concentration degree of industry and industry clusters...

Influence of information technology on social spatial behaviors of urban residents — Case of Nanjing City in China

Feng Zhen, Zongcai Wei

Chinese Geographical Science > 2008 > 18 > 4 > 316-322

Taking Nanjing as a case, the paper explains the spatial behavior differences existing in the information technology use among different groups of residents and households, by virtue of analyzing the survey data of urban households in the 11 districts of Nanjing, from the social, spatial, life and other non-technical angles. Also it makes various analyses and evaluation quantitatively and qualitatively...

Estimation of non-point source pollution loads under uncertain information

Ruzhong Li

Chinese Geographical Science > 2008 > 18 > 4 > 348-355

Many kinds of uncertainties are involved, such as random, fuzzy, grey, unascertained property and so on, in soil erosion process. To exactly predict the non-point source pollution loads, some uncertainties should be taken into consideration. Aiming at the deficiency of present blind number theory being helpless for fuzziness, a novel blind number, i.e. extended-blind number, was introduced by substituting...

Approach to modeling and virtual-reality-based simulation for plant canopy lighting

Haopeng Wang, Kai Zhao, Fengbin Song

Chinese Geographical Science > 2008 > 18 > 4 > 374-381

Over the past 20 years, significant progress has been made in virtual plant modeling corresponding to the rapid advances in information technology. Virtual plant research has broad applications in agronomy, forestry, ecology and remote sensing. As many biological processes are driven by light, it is the key for virtual plant to estimate the light absorbed by each organ. This paper presents the radiance...

Climate change and its effects on runoff of Kaidu River, Xinjiang, China: A multiple time-scale analysis

Jianhua Xu, Yaning Chen, Minhe Ji, Feng Lu

Chinese Geographical Science > 2008 > 18 > 4 > 331-339

This paper applied an integrated method combining grey relation analysis, wavelet analysis and statistical analysis to study climate change and its effects on runoff of the Kaidu River at multi-time scales. Major findings are as follows: 1) Climatic factors were ranked in the order of importance to annual runoff as average annual temperature, average temperature in autumn, average temperature in winter,...

Fuzzy synthetic evaluation of water quality of Naoli River using parameter correlation analysis

Jianhua Wang, Xianguo Lu, Jinghan Tian, Ming Jiang

Chinese Geographical Science > 2008 > 18 > 4 > 361-368

In order to improve the effectiveness of Fuzzy Synthetic Evaluation (FSE) models, a Parameter Correlation Analysis (PCA) was introduced into the FSE and a case study was carried out in the Naoli River in the Sanjiang Plain, Northeast China. The basic principle of the PCA is that the pairs of parameters which are highly correlated and linear with each other would contribute the same information to...

Sensitivity of penman-monteith reference crop evapotranspiration in Tao’er River Basin of northeastern China

Liqiao Liang, Lijuan Li, Li Zhang, Jiuyi Li, more

Chinese Geographical Science > 2008 > 18 > 4 > 340-347

A non-dimensional relative sensitivity coefficient was employed to predict the responses of reference crop evapotranspiration (ET₀) to perturbation of four climate variables in Tao’er River Basin of the northeastern China. Mean monthly ET₀ and yearly ET₀ from 1961 to 2005 were estimated with the FAO-56 Penman-Monteith Equation. A 45-year historical dataset of average monthly maximum/minimum air temperature,...

Cultural landscape evolution of traditional agricultural villages in North China—Case of Qianzhai Village in Shandong Province

Yangang Fang, Jisheng Liu

Chinese Geographical Science > 2008 > 18 > 4 > 308-315

Agricultural village is an important rural type in China. The evolution process and mechanism of its cultural landscape are different from those of the industrialized village. The paper focuses this theme by a case study of Qianzhai Village of Qufu City, Shangdong Province. In the case of Qianzhai Village, the evolution of its settlement has experienced three stages: mechanical expansion, sprawling...

Spatial-temporal pattern and population driving force of land use change in Liupan Mountains region, southern Ningxia, China

Bin Quan, M. J. M. Römkens, Jianjun Tao, Bicheng Li, more

Chinese Geographical Science > 2008 > 18 > 4 > 323-330

The Liupan Mountains is located in the southern Ningxia Hui Autonomous Region of China, which forms an important dividing line between landforms and bio-geographic regions. The populated part of the Liupan Mountains region has suffered tremendous ecological damages over time due to population pressure, excessive demand and inappropriate use of agricultural land resources. In this paper, datasets of...

Impact of labor transfer on agricultural land use conversion at rural household level based on Logit model

Taiyang Zhong, Xiuying Zhang, Xianjin Huang

Chinese Geographical Science > 2008 > 18 > 4 > 300-307

Since land and labor force are primary resources to be used and controlled by rural households, the allocation of labor forces will influence land uses, and further lead to land use conversion. The present study used the Binary Logit model to investigate the influence of labor force transfer, characteristics of rural households, location, and land market on agricultural land use conversion at rural...

Retrieval snow depth by artificial neural network methodology from integrated AMSR-E and in-situ data—A case study in Qinghai-Tibet Plateau

Yungang Cao, Xiuchun Yang, Xiaohua Zhu

Chinese Geographical Science > 2008 > 18 > 4 > 356-360

On the basis of artificial neural network (ANN) model, this paper presents an algorithm for inversing snow depth with use of AMSR-E (Advanced Microwave Scanning Radiometer-Earth Observing System (EOS)) dataset, i.e., brightness temperature at 18.7 and 36.5GHz in Qinghai-Tibet Plateau during the snow season of 2002–2003. In order to overcome the overfitting problem in ANN modeling, this methodology...
