Study On Methods To Land Intensive Use Of Development Zone In Less Development Area

Researching on land intensive use is a hot and key problem of the land scientific. It's fundamental means and method to solve conflict between the scarcity of land resources and economic development and protect the farmland especially the basic farmland. As the precursor of regional economy, development-zone plays a gathering, exemplary and diffusion effects. It's playing a pivotal role in promoting the rapid development of the local economy and has become the driver of the industrial upgrading and regional development and the base of technological innovation. But problems such as thinking much of expansion while ignoring the potential, emphasizing the scale while neglecting the efficiency and playing attention to attracting investment while overlooking the plan are still the most serious problems during land use. Chinese Development Zones'land use is inefficient and has a low level of land-intensive use, particularly in less developed regions. Thus, it's urgent to find the reasons for inefficient land use and solutions.This paper used obstacle amount assessment and comparative analysis to identify the limiting factors of land-intensive use in less development zone, described and analyzed methods maybe to realize land-intensive use of development zone, put ways and means forward to achieve its efficient and intensive use of land, and cased on Jiangsu Huai'an Economic Development Zone. Conclusions as following:(1) The results of obstacle amount assessment and comparative analysis are consistent, can systematically and objectively diagnose factors that affect land-intensive use, can well help researchers and managers to identify limiting factors in land-intensive use of development zone. But the obstacle is based on the land intensive use evaluation, the scientific and accuracy of the results depend on the scientific of the index system and rationality of the standard. While comparative analysis needs one or more zone with a higher degree of land intensive use to hold on the research, which requires large amount of data. And the authenticity of the data also has an impact on the results.(2) There are a lot of ways to achieve land-intensive use, including the legal, policy, economy. Different governments should choose one or more means to promote land intensive and efficient use according to the actual situations.(3) The case study results showed that land use structure, intensity of land-use and the input and output efficiency of industrial land are the limiting factors of Huai'an Economic Zone. It can choose the following five ways to strengthen and improve its land intensive use:1) optimize the land use structure, improve the ratio of industrial land; 2) optimizing the internal industrial structure and upgrade the industrial quality, increase input and output efficiency of land; 3) strictly implement the standard of land use, to improve land use intensity; 4) promote regional cooperation, to reference more advanced experience; 5) continue to strengthen the government management, build dynamic monitoring system for land use intensive.
