Abstract:

With the rapid economic development in the Pearl River Delta,a lot of problems appear in the utilization of land,especially,the reduction of cultivated land and environment pollution have become serious. From 1980 to 1994,the cultivated land in the delta decreased by 274.3thousand ha,and per capita decreased from 0.059 ha to 0.029 ha. Agricultural ecoenvironment is affected by pollution. Soil is gradually acidified,the PH value of 80% of land is lower than 5.5 and the fertility is also descending. With the fall of comparative benefit of agriculture,more and more arable land is left uncultivated. The relationship between the economic development and utilization of land resources has been getting dislocated.

Key words: Sustainable development, Land resources, The Pearl River Delta
