Land Reclamation Patterns of Rural Construction in Chongqing

To explore the similarities and differences patterns of project planning in different types of homestead land on rural construction land reclamation，questionnaire method was used.300 portion rural idled subsistence homestead lands were surveyed in three districts and counties of Chongqing city.According to the slope of land reclamation in position size，farmers land reclamation were divided into（0°-5°）flat type and（6°-25°）gradient types.The results showed that the same housing structure types on different areas and the different types on the same areas had the P1large differences in rural construction land reclamation of Chongqing city.And the different areas proportion of subsistence homestead land were similar，which the flat types of around 94% and gradient types of around 6%.Totally，there were also existed difference on the patterns of project planning that gradient types were more complex than flat types.The slope topography of Land reclamation was the very important factors on influencing the differences of project planning patterns.To solve the current problems that cover soil thickness，rock retaining sills，paths and irrigation canals and ditches designed unreasonable，planning principle and basic information of reclamation plot should be combined，and engineering planning and design should be scientifically reasonable.
