With rapid environmental degeneration and socio-economie development,the human settlement environment (HSE)has experienced dramatic changes and attracted attention from different communities.Consequently,the spatial-temporal evaluation of natural suitability of the human settlement environment (NSHSE)has become essential for understanding the patterns and dynamics of HSE,and for coordinating sustainable development among regional populations,resources,and environments.This study aims to explore the spatialtemporal evolution of NSHSE patterns in 1997,2005,and 2009 in Fengjie County near the Three Gorges Reservoir Area (TGRA).A spatially weighted NSHSE model was established by integrating multi-source data (e.g.,census data,meteorological data,remote sensing images,DEM data,and GIS data)into one framework,where the Ordinary Least Squares (OLS)linear regression model was applied to calculate the weights of indices in the NSHSE model.Results show that the trend of natural suitability has been first downward and then upward, which is evidenced by the disparity of NSHSE existing in the south,north,and central areas of Fengjie County. Results also reveal clustered NSHSE patterns for all 30 townships.Meanwhile,NSHSE has significant influence on population distribution,and 71.49% of the total population is living in moderate and high suitable districts.

Changes in Climatic Factors Influencing the Growth Period of Corn in Fengjie County

Asian Agricultural Research 2014年第12期6卷 82-84页

作者： Xiaozhen MAO Xinli MOU Chen MA Jiang HUANG Lin YUAN Key Laboratory of Water Environment Evolution and Pollution Control in Three Gorges Reservoir Chongqing Three Georges University

Under the background of global climate change,we analyze the change tendency of average temperature and amount of precipitation influencing the corn's growth period. The results show that from March to August,the monthly temperatures show an upward trend,but the rise is different in different months,and the maximum temperature rise is in May. Precipitation in different months has different trends. Climate change brings about favorable conditions at high altitudes in Fengjie,reduces production due to the temperature drop after the beginning of autumn,and increases the pressure on the corn supply.

The paper describes the land use situation in the project area from two aspects. Firstly, natural situation (landscape, temperature, soil hydrology, natural disasters); secondly, land use situation (land use structure, project construction scale, land area of different vegetation classes). Through the research on the land development and consolidation of Haiba Village of Fengjie County, the project is concluded and the implementation cases of the project are reduced from the following six aspects: land leveling project, water conservancy and irrigation, farmland road engineering, project management system, project funds management and completion and delivery of construction project. Besides, the social, ecological and economic interests obtained by the projects are analyzed, so as to provide reference for promoting land development and consolidation in the future.
