Effects of afforestation on carbon storage in Boyang Lake Basin, China
Chinese Geographical Science - Tập 23 - Trang 647-654 - 2013
By using field survey data from the sixth forest inventory of Jiangxi Province in 2003, the biomass and carbon storage for three studied species (Pinus massoniana, Cunninghamia lanceolata, and Pinus elliottii) were estimated in Taihe and Xingguo counties of Boyang Lake Basin, Jiangxi Province, China. The relationship between carbon density and forest age was analyzed by logistic equations. Spatio-......
Spatial and Temporal Changes of Arable Land Driven by Urbanization and Ecological Restoration in China
Chinese Geographical Science - Tập 29 - Trang 809-819 - 2019
Since the industrial revolution, human activities have both expanded and intensified across the globe resulting in accelerated land use change. Land use change driven by China’s development has put pressure on the limited arable land resources, which has affected grain production. Competing land use interests are a potential threat to food security in China. Therefore, studying arable land use cha......
Experimental research on quantitative inversion models of suspended sediment concentration using remote sensing technology
Chinese Geographical Science - Tập 17 - Trang 243-249 - 2007
Research on quantitative models of suspended sediment concentration (SSC) using remote sensing technology is very important to understand the scouring and siltation variation in harbors and water channels. Based on laboratory study of the relationship between different suspended sediment concentrations and reflectance spectra measured synchronously, quantitative inversion models of SSC based on si......
Analysis of historical formation of agricultural areas in Sichuan basin and geographical factors
Chinese Geographical Science - Tập 7 - Trang 30-38 - 1997
The earliest agricultural activities in Sichuan Basin can be traced back to the middle Neolithic Age. During the development process afterwards, the Qin and Han dynasties, the Sui and Tang dynasties, and the Northern Song Dynasty were three peaks of agricultural development. The various natural conditions resulted in a variety of agricultural patterns in Sichuan Basin. The drainage system played a......
Spatio-temporal variability of soil water at three seasonal floodplain sites: A case study in Tarim Basin, Northwest China
Chinese Geographical Science - Tập 24 - Trang 647-657 - 2014
The floodplain vegetation of the Tarim River in Northwest China is strongly influenced by irrigated agriculture. The abstraction of river water disturbs the natural dynamics of the floodplain ecosystem. The human impact on the hydrological system by bank dams and the irrigation of cotton plantings have caused adverse changes of the Tarim River and its floodplains, so the current stocks of the typi......
Sandy Land-lake-vegetation Landscape of Songnen Sandy Land of China: Pattern, Process and Mechanism
Chinese Geographical Science - Tập 32 - Trang 580-591 - 2022
In order to investigate the dynamic evolution of the sandy land-lake-vegetation landscape in Songnen Sandy Land (SSL) and its response to climate change and human activities, the distribution pattern, evolution, and driving mechanisms of the landscape were analyzed based on Landsat satellite images and meteorological and socio-economic data during 1980–2020. The results indicate that the area of s......
Review of shadow detection and de-shadowing methods in remote sensing
Chinese Geographical Science - Tập 23 - Trang 403-420 - 2013
Shadow is one of the major problems in remotely sensed imagery which hampers the accuracy of information extraction and change detection. In these images, shadow is generally produced by different objects, namely, cloud, mountain and urban materials. The shadow correction process consists of two steps: detection and de-shadowing. This paper reviews a range of techniques for both steps, focusing on......
Conceptualizing and measuring economic resilience of resource-based cities: Case study of Northeast China
Chinese Geographical Science - Tập 27 - Trang 471-481 - 2017
This paper develops a conceptual model and an indicator system for measuring economic resilience of resource-based cities based on the theory of evolutionary resilience and the related concepts of persistence, adaptation, and transformation. Nineteen resource- based cities in Northeast China were analyzed using the indicator system. The results showed that Liaoning and Jilin provinces had higher e......
Spatial gradient analysis of urban green spaces combined with landscape metrics in Jinan City of China
Chinese Geographical Science - Tập 15 - Trang 254-261 - 2005
Urban green spaces have been arisen growing concern responded to the social and environmental costs of urban sprawl. A wide range of planning and policies has been and/or will be designed to protect urban green spaces and optimize their spatial pattern. A better design or planning of urban green space can make a major contribution to quality of environment and urban life, and furthermore can decid......
Transportation characteristics change under rapid urban expansion: A case study of Shanghai
Chinese Geographical Science - Tập 20 - Trang 554-561 - 2010
This paper focuses on the economic development and urban morphology as well as its impact on the transportation system during the urban expansion of Shanghai in the last more than 20 years (1986–2008). Based on data from 3 comprehensive transport surveys of Shanghai since 1986, the changes in residential trip demand, vehicle use, and the spatial distribution of trips were studied to understand the......
