2000~2020年南宁市森林生态系统质量评估

Assessment of Forest Ecosystem Quality in Nanning from 2000 to 2020

森林生态系统质量影响着人类的生活质量和社会的可持续发展,生态系统质量的客观评价具有重要意义。研究参照生态系统质量评估技术规范,对其具体的数据处理细节做了一定调整,应用调整后的技术方法对南宁市2000~2020年森林生态系统质量开展评估,并分析调整后技术方法的适用性。评估结果表明:在评估时段,南宁市森林生态系统质量指数在54.148~74.355之间,总体保持在良好等级,2020年的森林生态系统质量指数值接近优等标准;评估结果具有良好的可视化特性,可以清晰地展示不同时间段生态系统质量指数及等级变化特征;评估结果具有较好的应用价值,可以应用于生态功能区域评估、专题评估、服务生态环境监管等方面。通过对该技术方法的实际应用研究,认为生态系统质量评估技术规范具有较高的应用价值,可广泛应用于具体的评估业务,为生态环境监管业务提供技术支撑。

The quality of forest ecosystem affects the quality of human life and the sustainable development of society.The objective evaluation of forest ecosystem quality is of great significance According to the technical specifications for ecosystem quality assessment,the study made some adjustments to the specific data processing details,applied the adjusted technical methods to assess the forest ecosystem quality of Nanning from 2000 to 2020,and analyzed the applicability of the adjusted technical methods.The evaluation results showed that the forest ecosystem quality index of Nanning is between 54.148 and 74.355 during the evaluation period,which is kept in a good grade,and the forest ecosystem quality index in 2020 was close to the excellent standard.The evaluation results have good visual characteristics which can clearly show the characteristics of ecosystem quality index and grade changes in different time periods.The evaluation results have good application value,which can be applied to regional ecological function assessment,thematic assessment,service ecological environment supervision and so on.Through the practical application of this technology,it is considered that the technical specification of ecosystem quality assessment has high application value,and can be widely used in specific assessment business to provide technical support for ecological environment supervision business.
