土地利用可持续发展位理论构建与应用

摘要/Abstract

摘要： 结合土地利用生态位理论和可持续发展理论,构建了土地利用可持续发展位理论,其核心内容包括土地利用可持续发展基本位、理想位、优势位、关键位和土地利用可持续发展位空间概念及模型。以甘肃省为例,测算确定了甘肃各地州市建设用地与新增建设用地可持续发展位空间。甘肃各地州市建设用地除了嘉峪关、金昌市指标值超出可持续发展位空间外,其余各地州市建设用地控制指标均处于可持续发展位空间内。白银、武威、张掖、酒泉、庆阳、甘南的指标值接近于理想目标;天水、平凉、定西、陇南、临夏的指标值趋近于适度目标。新增建设用地可持续发展位空间结果除平凉市和甘南州外,其余各地州市的控制指标均处于新增建设用地控制指标与其可持续发展位空间之间。表明《甘肃省土地利用总体规划（2006—2020）》确定的各地建设用地与新增建设用地控制规模基本均处于可持续发展位空间范围。甘肃省的实践证明,土地利用可持续发展位理论可用于系统研究土地生态系统变化规律,指导土地资源的可持续利用。

Abstract: Based on theories of sustainable development and niche of land use, land use sustainable development position theory has been constructed, and its core contents include concepts of sustainable development basic position, sustainable development ideal position, sustainable development advantageous position, sustainable development critical position, sustainable development position threshold, and land use sustainable development position model. We calculated sustainable development position threshold values for construction land and newly-increasing construction land control in the cities of Gansu province. Results showed that construction land control target values in the cities of Gansu province were not more than land use sustainable development threshold values except for in Jiayuguan city and Jinchang city, and the target values in Baiyin city, Wuwei city, Zhangye city, Jiuquan city, Qinyang city and Gannan autonomous prefecture were close to the ideal goals, while those in Tianshui city, Pingliang city, Dingxi city, Longnan city and Linxia autonomous prefecture tend to appropriate goals of land use. The newly-increasing construction land control target values of the cities are all between the ideal goals and appropriate goals of land use except for in Pingliang city and Gannan autonomous prefecture. It showed that the control target values of construction land and newly-increasing construction land in Gansu, which had been determined in general land use planning in Gansu province during 2006—2020, were basically not more than land use sustainable development threshold values. The practice in Gansu province proves that land use sustainable development position theory can be used to study land ecological system change rule, and guide the sustainable use of land resource.

Key words: niche of land use, land use sustainable development position, sustainable development position threshold
