On the Landscape Activity Measure Coupling Ecological Index and Public Vitality Index of UGI: The Case Study of Zhongshan, China

In the context of high-quality urban development and increasingly important role green infrastructure (UGI) in public life, landscape activity (LA) has gradually become a dominant indicator for improving UGI quality efficiency, as well optimizing its environmental friendliness meeting recreational needs public. Relevant studies have shown that ecological index (EI) vitality (PVI) can characterize LA from perspectives greening activities, respectively, their simultaneous analysis provide professional judgment quantitative technical approaches UGI. At same time, with support remote sensing, big data, GIS, other spatial information model coupling EI PVI to be developed. First, this article established research framework activity, by combining sensing location-based services (LBS) technology, measurement strategy suitable coupled was formed. Then, based on MATLAB platform entropy-weighted TOPSIS model, developed fusion algorithm establish taking central area Zhongshan case study. Finally, four-quadrant classification grading were ArcGIS platform. Empirical showed study about 176.43 km2, 160 units identified. The minimum value is 0.06, maximum 0.85. divided into three grades: low (0–0.24), medium (0.24–0.46), high (0.46–0.85). Among them, top 5% mainly correspond parks waterfront greenways, bottom islands farmland. distribution four quadrants relatively balanced: among number developing types largest, accounting 29.4%, mature least, 20.0%. This forms concise process UGI, which used evaluation. It expected result will significant construction sustainable terms exploration.
