利用地理国情普查数据开展生态环境质量评价——以宜宾市为例

Ecological Environmental Quality Assessment based on Census Data of Geographical Conditions

生态环境评价方法有很多,包括图形叠置法、生态机理分析法、类比法、质量指标法、景观生态学方法等。然而,除了生态环境评价方法及指标体系对最终结果产生影响外,作为参与评价因子的基础数据,由于其数据质量的差异也会带来很大的影响,对客观评价、科学认识区域生态环境具有较大影响。因此,笔者从生态环境调查、评价、分析的数据源出发,提出了利用地理国情数据开展生态环境评价分析的基本方法。技术流程简单,基础数据扎实,易于推广复制,也是未来常态化地理国情监测的重要方向之一。

There are many ecological environment assessment methods,including graphic overlay method,ecological mechanism analysis method,analogy method,quality index method,landscape ecology method,etc.. However,in addition to the ecological environment evaluation index system and method of impact on the final results,as the basis of the data in the evaluation factor,due to the difference of the quality of the data will have a big impact,the objective evaluation,scientific understanding of the regional ecological environment has a great influence. Therefore,from the data source of ecological environment investigation,evaluation and analysis,the author puts forward the basic method of ecological environment evaluation and analysis by using geographic national conditions data. The technical process is simple,the basic data is solid,easy to promote replication,is also one of the important directions of the future normalization of geographic conditions monitoring.
