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.
