| 摘 要： | 本文主要探讨了粮食安全、土地开发适宜性以及综合生存环境等不同条件约束下的珠江三角洲建设用地最大供给量与供给约束。其结果表明，珠江三角洲地区建设用地开发利用极限为(97.12～110.57)×104hm2,占全区土地总面积的23.30%～26.52%，其中尚未建设利用部分为(21.08～34.53)×104hm2。如果参照1997年～2004年各市年均新增建设用地的话，全区平均尚未建设利用的土地最多只能供给13年使用，其中珠海、佛山和中山只能供给3年～4年，深圳和东莞只能供给7年～8年，广州只能供给约13年；如果再考虑用地区域与供地区域可能不重叠的话，则土地可供时间更短，上述诸市很快将陷入无地可供的境地。惠州、肇庆和江门是珠江三角洲为数不多的3个可建设用地比较充裕的地区，但随着经济发展的不断加快并伴随着建设用地的不断扩大，其土地资源的有限性与经济社会发展之间的矛盾也将逐渐突显。从建设用地开发利用极限看土地供给，珠三角多数城市可供建设的土地资源显得十分匮乏。将来的发展必须从严控制土地供应，科学合理地设置土地供应门槛，提高建设用地效率与质量。

| Abstract: | This paper discusses the availability of land for construction use in the Pearl River Delta, with restrictions based on food security, use suitability and the need for an integrated life-support environment. Analysis based on food security restrictions shows that if land use conforms to the government-s Regulations on the Protection of Basic Farmland, then a baseline of farmland will be maintained. An analysis based on suitable use and integrated life-support environment factors shows that the maximum land area available for construction use in the Pearl River Delta is from 97.12×104 hm2 to 110.57×104hm2, 23.30 to 26.52 percent of the total area. The currently undeveloped portion totals 21.08×104hm2 to 34.53×104hm2. Based on the rate of urban expansion from 1997 to 2004, unused construction land in the PRD will be used up in no more than 13 years. Depletion of available construction land is projected to occur in Zhuhai, Foshan and Zhongshan in 3 to 4 years, in Shenzhen and Dongguan in 7 to 8 years, and in Guangzhou in 13 years. Since land use and land supply are not perfectly matched, we assume that land supply will be depleted even more rapidly than estimated and cities in the PRD will soon experience a shortage of land. Although other cities in the Pearl River Delta, including Huizhou, Zhaoqing and Jiangmen, have a relatively abundant supply of land available for construction, there will also be conflicts over land resources due to rapid economic growth and the increasing use of land for construction. Overall, the supply of land for construction use in most cities of the Pearl River Delta is quite limited. There should be strict control of the land supply in order to improve the efficiency and quality of land use. |
