“…Current studies on ECR effects on ecological conservation mostly focus on qualitative analysis, and their perspectives and methods are limited (Hou et al, 2018;Wang et al, 2021;Yang and Xie, 2021;Zeng, 2021;Yue et al, 2022). Studies have been conducted to evaluate the ecological benefit, environmental impact, human disturbance activity, and ecological security patterns by constructing indicator systems, calculating ecosystem service values, landscape pattern index, and normalized difference vegetation index (NDVI) (Bailey et al, 2021;Bai et al, 2018;Chen et al, 2021;Yang and Xie, 2021;Yang and Qiao, 2023); and to assess the ecosystem value, carbon sequestration function, water conservation, soil conservation and biodiversity, and ecosystem health after ECR delineation (Jia et al, 2018;Yu et al, 2020;Nelson et al, 2009;Jiang and Wu, 2021;Zheng et al, 2022). However, studies comparing habitat changes inside and outside the ECR and before and after ECR delineation remain lacking.…”
