摘要/Abstract

摘要： 在地理信息技术和遥感数据支持下,对甘肃省2000和2010年的生态资产价值及其空间分布格局进行了定量测度。构建空间生态资产价值经济协调度模型,测算了甘肃省生态资产价值与经济发展水平协调状况。结果表明：1）甘肃省生态系统在2000和2010年的生态资产价值分别为2 430.84×10⁸和2 487.40×10⁸元;2）林地对甘肃省生态资产价值的贡献量最大;陇南市和甘南州的生态资产价值占甘肃省总价值的一半左右;3）生态资产价值的空间分布整体上呈现西北低、东南高的特征,11 a间生态资产价值增加较多的区域主要分布在河西走廊中部和陇东;4）11 a间,甘肃省各市州生态资产价值与GDP比值均出现不同程度的减小,生态资产价值增长与GDP增长不协调;5）生态-经济协调分区中,潜在危机区的面积最大,其次是低度冲突区和关系恶化区。

Abstract: With the fast development of socio-economic, more attention has been focused on the property value of natural resources and environmental benefit. In this regard, Ecological Property Value (EPV), which is considered as one of the most significant resource and wealth in a country, has being concerned more and more in recent years. EPV is one of the bases of social development. Understanding the EPV in a region is very useful in taking effective management to improve the sustainable development. So, it is very important to assess the EPV. Massive vector and raster spatial data are analyzed in the environment of GIS software. Remote sensing data sets, as well as meteorological data, NDVI and GDP, are resampled at a spatial resolution of 1 km. The EPV and its spatial-temporal variation in Gansu Province from 2000 to 2010 are evaluated and the spatial distribution maps of EPV are drawn. This paper develops spatial model of Ecological Economic Harmony (EEH). The EEH is developed to reflect the coordination degree of the EPV and GDP. The results show: 1) The overall amount of EPV in Gansu Province are 2 430.84 billion and 2 487.40 billion in 2000 and 2010 respectively. 2) The forest ecosystem offers the most of EPV. About half of the total EPV in Gansu Province is contributed by Longnan and Gannan. 3) The spatial distribution of EPV in Gansu Province exhibits a declining trend from southeast to northwest, and the EPV in the Hexi Corridor and Longnan area increased rapidly from 2000 to 2010. 4) The ratios of the EPV to GDP in most of cities decreased in different degrees, which shows unmatching of the development of the EPV and the growth of GDP and the tremendous pressure of protection of ecological environment. 5) The present pattern of the coordination of ecological and economic systems expresses that the potential crisis zone occupies the central location and has a broad coverage, followed by low-grade conflict zone and initial degradation zone. There are some uncertainties for evaluating EPV based on quantitative remote sensing retrieval and economic evaluation methods. The uncertainties are mainly from two aspects: the EPV and the criteria for evaluation, and the spatial resolution of remote sensing data and the precision of applied ecological model.

Key words: eco-economic harmony, Gansu Province, ecological property value (EPV)
