Research On The Economic Benefit Appraisal Of Construction Land Use In Yellow River Delta

The Yangtze River Delta, Pearl River Delta and the Yellow River Delta is the three largest river delta of China. The Yangtze River Delta and the Pearl River Delta has been completely developed . The development of Yellow River Delta became national strategic development plan in 2009, which marks the last river delta going to be developed in China. The land has always been the basic material of our human survival and development as well as the carrier of social and economic development. With the development and construction of the Yellow River Delta, the demand of land, especially land for construction ,will increase, but the supply of land resources are limited, it is difficult to meet the demand of the land for construct under the premise of ensuring the amount of cultivated land. Therefore, it is necessary to research on the current land use efficiency evaluation.In this paper, construction land use of the Yellow River Delta is evaluated on the economic point. First, the theories and methods relevant to the efficiency evaluation of land use is summarized, and current status and trends is comprehensively analyzed, which is based on the environment of the Yellow River Delta, the factors that affect the use of construction land is summed up. Then, an index system is build up, what can evaluate construction land scientific and feasible which based on the human, financial, and material inputs and economic outputs. Finally, the economic benefit of construction land use is evaluated with the method of DES during 2000-2008. Through the analysis of the results, lots of devices to rise construction land use of the Yellow River Delta is presented, as well as a theoretical basis of the Yellow River Delta's construction.
