长江三角洲地区土地资源开发强度评价研究

Evaluation on Exploitative Intensity of Land Resources in the Yangtze River Delta Region

研究了土地资源高强度开发与长江三角洲地区开发强度评价问题，运用理论阐释与定量分析评价，指出土地开发强度的内涵并提出相应的量度方法，界定了“土地资源高强度开发”的科学定义，揭示出长江三角洲地区土地开发利用在国内层面属于高强度开发，而与国外典型地区相比则属于低强度开发。提出长江三角洲地区土地高强度开发的对策在于改善开发技术与人文环境，强化区域内部低强度单元的开发强度，坚持综合、高效、持续性三结合原则开发利用水土资源，并强调利用与整治并重。

The exploitative intensity of land resources in Yangtze River Delta region has been discussed in this paper. Through interpretation in terms of theory and quantitative evaluation, the implication of land exploitative intensity is stated clearly, and relative measurement method is put forward. 'High intensity exploitation of land resources' is defined scientifically. It shows that land exploitative intensity grade in Yangtze River delta is high intensity in country, and that its grade is low intensity in the world. The authors put forward the ways to deal with land high intensity exploitation in the Delta, such as the improvement of exploitative technology and human environment, the strengthening of exploitative intensity of low-grade units in the region, and the exploitation of water and land resources by sticking to principles of integration, high efficiency and lastingness. In the same time, the authors emphasize that utilization and protection are both important.
