Abstract: The Yangtze River Delta is one of the most developed areas in China, but the land area per capita is only 0.135 ha, and the cultivated land per capita is 0.045 ha, far less than 0.078 ha, the mean value of the whole country. Moreover, substantial cultivated land has been converted for other purposes, and soil has been polluted. As a result, land degradation occurred, some excellent land has been wasted with low utilization rate.In order to attain sustainable development, land resources must be sustainably used. First, as far as agricultural land is concerned, maintenance and utilization must be done in a combined way to improve the yields of cultivated land. Furthermore, land resources in the mountain areas must be comprehensively used, and the agricultural structure be readjusted. Second, as for land for non agricultural usage,urban land must be intensively utilized, the town and township enterprises and the villages be rationally planned and distributed, and the tourist land be well developed. Finally, but not least, the relationship between the agricultural and non agricultural land must be rationally readjusted.
