摘要:

在山西省1978—2001年的人均生态足迹、生态承载力、生态赤字计算的基础上,对生态足迹的3项指标进行了数量、结构、动态变化规律及其原因分析。结果表明:山西省该时期的多年人均生态足迹2.075 hm2,超出了2.0 hm2的全球生态阈值;平均人均生态承载力0.877 hm2,远低于1.6 hm2全球生态标杆。多年平均生态赤字是生态承载力的1.38倍,处于相对不可持续的状态,并有逐步扩大的态势。导致这一结果的原因,一是由于人口的不断增长、耕地的持续减少、能源消耗的快速增加和人民生活消费品市场进一步扩大,以及煤炭等矿产资源的长时间、大面积、高强度开采,电力工业的快速发展使生态足迹量大幅增加;二是山西省耕地整体质量差、生态生产力低下,未利用地面积过大,使土地生态承载力低下。因此,加强中低产田的改造、加大以荒山荒坡造林为主的生态建设力度是提高全省可持续发展能力的重要措施。

Abstract:

This paper, based on Shanxi’s 1978-2001 ecological footprint, capacity and deficit per capital, analyzes their counts, structure and dynamic changes and causes in three indexes, which shows an average ecological footprint of 2.075 hm2, over the global threshold 2.0 hm2, an average capacity of 0.877 hm2, far below the global standard of 1.6hm2, and an average of ecological deficit 1.38 times of capacity, unsustainable and expanding. The causes lie in rising population, decreasing farmlands, fastconsuming energy, long-term, large scale mining of coal, and fast-developing power industry, and in poor quality of farmland, low productivity, large unused area. The paper presents approaches to sustainable development in reconstructing low productive farmlands and intensifying ecological construction with a focus on forestation.

Key words: ecological footprint, ecological capacity, ecological deficit, dynamic changes
