Study on GIS Visualization in Evaluation of the Human Living Environment in Shenyang-Dalian Urban Agglomeration

الملخص EN

Analysis of human living environmental quality of Shenyang-Dalian urban agglomerations has important theoretical and practical significance in rapid development region.

A lot of investigations have been carried for Shenyang-Dalian urban agglomerations, including 38 counties.

Based on the carrying capacity of resources, natural and socioeconomic environmental factors and regional changes of human living environmental evaluation are analyzed with the application of geographic information systems (GIS) software.

By using principal component analysis (PCA) model and natural breaks classification (NBC) method, the evaluation results are divided into five categories.

The results show that the human living environmental evaluation (HLEE) indexes of Dalian, Shenyang, and Liaoyang are higher than other counties.

Among these counties, the human living environmental evaluation (HLEE) indexes of coastal counties are significantly higher than inland counties.

The range of the human living environmental evaluation index in most of the study area is at III, IV, and V levels, accounting for 80.01%.

Based on these results, it could illustrate the human living environment is in relatively suitable condition in Shenyang-Dalian urban agglomeration.
