基于土地利用信息的区域可持续发展评价方法

    Evaluation method of regional sustainable development based on land use information

    • 摘要: 综合考虑强调人为活动影响的生态足迹与强调自然资源影响的生态服务价值2种方法的优势,提出了基于土地利用信息的区域可持续发展评价方法。以江西省为例,遥感解译得到1990、2000、2008年 3个时期的土地利用动态变化信息;以土地利用/覆盖为主要数据,结合其它辅助数据,分别计算了江西省3个时期的生态足迹与生态服务价值;以生态足迹与生态服务价值计算结果为基础数据,构建了基于土地利用信息的区域可持续发展评价指数,评价了江西省3个时期的可持续发展状况。结果表明,在研究时段内,江西省虽然从自然资源提供生态服务的能力上看仍然处于良好状态,但是人为活动扰动已经在向不可持续方向发展,可持续发展评价指数评估显示了江西省可持续发展的不利趋势。原因在于江西省生态服务价值的增加速率较生态赤字慢,江西省的可持续发展更多地受人为活动影响。该研究可为江西省的可持续发展提供参考依据。

       

      Abstract: Considering the advantages of the ecological footprint emphasizing the effect of human activities and ecosystem service value emphasizing the influence of natural resources, the method of assessment of regional sustainable development was proposed based on land use information. Taking Jiangxi province as a case, land use dynamic change information was acquired by interpreting remote sensing images in three years of 1990, 2000 and 2008.The ecological footprint and the value of ecosystem services in the three periods were calculated on the land use data. Regional sustainable development assessment index were selected based on land use information, and the sustainable development was evaluated in the three periods. Results showed that although the capacity of provide ecological services was in good condition in the study period, disturbances human activities had caused the region unsustainable development. Sustainable development assessment index displayed the negative trend of sustainable development. The reason was that the increasing rate of the value of ecosystem services was slower than that of the ecological deficit. The sustainable development was mostly impacted by human activities. This research could provide the theoretical and reference basis of sustainable development of Jiangxi province.
