摘要: 分析了长江三角洲地区自然、社会经济条件以及土地问题的主要症结,提出该区土地可持续利用对策。对于农业用地,应采取用地与养地相结合的措施,提高耕地产量,并提高山区土地利用率,综合开发土地后备资源,合理调整农业结构;对于非农用地,应集约利用城镇土地,调整乡镇企业与农村居民点的布局,合理开发旅游用地;同时必须协调好农业用地与非农用地的关系。

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.

Key words: land resources, sustainable utilization, Yangtze River Delta
