“…Therefore, we generated the zoning map in habitat protected areas by integrating the habitat quality in 2000 and 2017, as well as the variation in HQI between 2000 and 2017. The evaluation processes were: (1) extracting 20% and 40% of the study areas with the largest HQI values and dividing the areas into three grades based on relevant studies about assessing Ecological Conservation Redline and the actual situation in Shanghai 38,39 . (2) Grading habitat quality variations from 2000 to 2017 by a criterion of [− 1 to 0.2), [0.2-0.8), and [0.8-1) considering the effectiveness of the ecological space construction and optimization projects in Shanghai between 2000 and 2017; (3) adding up all three index values in ArcGIS 10.8 and manually grade the total index value with consideration of their relative importance to maximize the representativeness and effectiveness of habitat conservation; (4) removing the fragmented patches with an area less than 10 hm 2 , as fragmented habitats with an area less than 10 hm 2 are easier to influenced and filled by built-up land 40 .…”

Habitat quality has been widely used as an important indicator in the evaluation of regional ecological security and ecosystem services. Previous studies have focused on the influences of urbanization on habitat quality, but the protection measures about how to respond to the dynamic changes of habitat quality patterns are still unclear. This study investigated the habitat quality in the metropolitan region of China (Shanghai) by using InVEST model, and analyzed its dynamic changes from 2000 to 2017 for the sake of providing different protection objects and measures for Shanghai. The results showed that the habitat quality index (HQI) in 2017 was 0.42, and the accumulated area percentages of less than 0.4 in HQI reached 46%, whereas the habitat quality in Chongming district was the highest. The HQI and habitat protected index (HPI) showed an obvious decline tendency from suburban area to downtown area. The HQI in Shanghai gradually declined from 0.56 in 2000 to 0.42 in 2017, and the deterioration area in habitat quality nearly covered 33% between 2000 and 2017. Additionally, the area proportion of the median habitat quality (0.4 < HQI ≤ 0.6) drastically dropped, but the areas of the low (HQI ≤ 0.2) and the high (HQI > 0.8) in habitat simultaneously expanded. Therefore, the valuable habitat in the western and southern coastal wetlands, Dianshan lake and Chongming district in Shanghai should be strictly protected, which covered 30% of the metropolitan area in Shanghai, and about 17% of the region located in the inner coastal zones and northern of Chongming Island was in urgent need of habitat restoration. Our results provide vital references for the maintenance and sustainable management of urban habitats in the metropolitan region.
