摘要
区域性、综合性的生态环境质量评估,其评估结果基本上是得出一个综合性的结果值,无法清晰的反映出区域内部连续性的空间变化特征,生态系统质量评估技术规范确定的以植被遥感生态参数作为指标构建的评估及分级方法,既可以呈现区域评估总体结果,也能实现空间上连续性表达。将该方法应用于南宁市中心城区的生态系统质量评估中,可以较好的呈现评估区域内部评估单元的总体结果、生态系统质量指数的空间连续性变化特征,能够直观的判读其开发建设趋势,城市生态系统质量提升改善的区域分布,得出的评估结果具有一定的参考价值,认为该方法可适用于城市区域的生态系统质量评估之中。
The regional and comprehensive ecological environmental quality assessment results are basically a comprehensive result value,which can not clearly reflect the spatial change characteristics of the regional internal continuity,the assessment and grading method based on vegetation remote sensing ecological parameters defined in the technical standard of ecosystem quality assessment can not only present the overall results of regional assessment,but also realize the spatial continuous expression.In this study,the method is applied to the ecosystem quality assessment of the central city of Nanning,which can present the overall results of the assessment units in the region and the spatial continuous change characteristics of the ecosystem quality index,to be able to visually interpret its development and construction trends,the regional distribution of city ecosystem quality improvement and improvement,and the evaluation results obtained have certain reference value,it is concluded that the method can be applied to ecosystem quality assessment in city areas.
