荥经县生态资产评估及动态演变

Evaluation and Changing Analysis of Ecological Assets in Yingjing County

  • 摘要: 以雅安市荥经县为例,以1990年、2000年、2010年、2015年四期的Landsat5 TM影像为数据源,运用生态系统服务价值法,对其25年来的生态资产总量及变化情况进行了测算。结果表明:全县生态资产总量持续增加,各项服务功能贡献较为平均;各种土地利用类型的生态资产贡献率差异较大,耕地资源并未得到良好的保护,严重缩小了食物来源;在未来的发展中,应在继续维持相关服务功能的基础上,合理开发和利用土地,进一步加强对耕地资源的保护,不断提升全县生态资产价值。

     

    Abstract: In this paper,taking Yingjing County as an example,its ecological assets amount was measured by means of ESV method based on the aerial remote sensing images in 1990 and 2015.The results showed that the ecological assets amount continuosly increased;The contribution rate of service functions was relatively average; Ecological assets contribution rate of different land use types was bigger;Cultivated land resource had not been well protected,which led to the narrowing of the food source.In the future,the rational development and utilization of land,and protection of cultivated land resources would be needed for promoting the ecological assets value.
