Cangzhou Binhai District, Saline-alkali Soil Consolidation Models

More than at any time in the past, contradictions between demand and supply of cultivated lands nowadays become greater. With fast growth of Population and economic, our demand of cultivated lands is becoming larger and larger, however, there are less and less cultivated lands. In order to solve this problem, on the one hand we should control the quantities of population to reduce the aggregate demand; on the other hand increase quantity of output through improving the amount or quality of cultivated land. Land assembly contains these two levels of activities. Which generally means exploitation and re-cultivation of agricultural land. It can increase the quantity of available land, meanwhile it can also improve utilization ratio and output rate of land resource, guarantee the benign cycle of economic, social and environmental benefits.Saline-alkali soil is distributed widely in our country. Putting the saline-alkali soil in order means to increase cultivated land resource, which is one important part of land assembly. It can also guarantee safety of food supply, raise utilization ratio of land resource, protect and improve ecological environment, advance agricultural and rural modernization, strengthen fundamental positions of agriculture, etc.This text, at the background of energetically advocate land assembly both at home and abroad, at support of government investment key item funds of "Land assembly project of Xindian town in Mengcun Hui Autonomous County", made a general survey of the domestic and international land assembly's theory and practice, synthesized multi-disciplinary knowledge, such as land science, economics, ecology, geography, geographical information science, etc, integrated theory with practice, put land assembly case study into salt and alkaline land of Cangzhou coastal area, explored at length in land assembly design and put forward constructive suggestions.The introduction included the background, the meaning, the develop of the research. Based on the existent problem and development trend, the author point out the content and goal of the thesis.In the second part, the author bring forward mode of land assembly in salt andalkaline land area, it includes concept and mode of land assembly, mode of plan design and engineering design in the coastal area, etc.In the following part, founded on project of "Land assembly project of Xindian town in Mengcun Hui Autonomous County ", the author explored the mode of design of the plan.Finally summarized the thesis, pointed out the achievements and insufficiencies of the thesis, and put forward the reasonable suggestions to the questions that exist at present.This result of the research had great value in salt and alkaline land assembly in coastal areas, it also had instructive value in others land assembly projects.Innovative points of this paper:1 .Brought forward the mode of land assembly in salt and alkaline land of coastal areas, studied at length in land assembly design and put forward constructive suggestions.2.Explored the suitable mode according to difference approach of raising moneyand develop level of economic in diverse regions.
