Evaluation of the heterogeneity in the intensity of human interference on urbanized coastal ecosystems: Shenzhen (China) as a case study

Quantitative measurement of the heterogeneity in the intensity of human interference is key to accurately assessing the impact of human activity. The same human activities in different landscape configurations should have different impacts. This study constructed a weighted analysis to describe and measure heterogeneity under the Hemeroby index model framework, based on gradient structures analysis of coastal landscape patterns and dynamic changes in landscape patterns. Shenzhen’s coastal landscape in 2015 was selected as a case study for this method. The results showed heterogeneity in the intensity of human interference that meaning more information with clearer details. The intensity of human interference was generally stronger in the west than in the east. High-intensity human (0.95) were continuously distributed in the west, while in the east these were scattered in towns, ports, coastal beach resorts, etc. The highest intensity human activities were clustered in the 6 km band, and from here these decreased inland but increased to the coastline. The lowest intensity human activities were clustered in the east of the 2 km band.
