Spatial and temporal evolution of landscape ecological health in Naolihe Basin
【Objective】This study aimed to reveal the temporal and spatial evolution characteristics of watershed landscape ecological health, clarify its spatial differentiation and clustering, and provide targeted suggestions and theoretical references for the conservation and sustainable development of watershed landscape ecological resources.【Method】Based on landscape ecological structure, process and function, this study constructed a landscape ecological health evaluation index system. The mixed model of analytic hierarchy process (AHP) and entropy weight method (EWM) were used to determine the index weight. Weighted overlay analysis, health rank transfer matrix, and exploratory spatial data analysis (ESDA), using ArcGIS 10.7 and GeoDa 1.14 platforms, were used to study the temporal and spatial evolution of ecological health and spatial correlations in the landscape of the Naolihe Basin in 2010 and 2018.【Result】Research shows that from 2010 to 2018, the Naolihe Basin landscape ecological comprehensive health index average dropped from 0.67 (level Ⅳ, sub-healthy) to 0.59 (level Ⅲ, moderately healthy). The transformation of landscape ecological health level was dominated by the transformation of adjacent levels. Among the transformation types, the stable type accounted for the largest proportion, whereas the improved type accounted for the smallest proportion. Compared with the improved type, the degraded type was 9.69% larger in proportion and 2 184.67 km2 larger in area, with only minor improvements in the northern part of Baoqing County, the majority of Jixian County, and the northeastern part of Youyi County. In 2010, the ecological health of the basin landscape showed strong spatial agglomeration, which was weakened in 2018, and spatial autocorrelation analysis showed the spatial location and scope of spatial differentiation and aggregation characteristics of landscape health in the basin from 2010 to 2018.【Conclusion】The spatial distribution of the landscape ecological health index in the Naolihe Basin was generally high in the east and low in the west during both periods, and the study area as a whole showed a pattern of improvement in the west and degradation in the east and southwest. According to the different spatial autocorrelation transfer types of landscape ecological health in the study area from 2010 to 2018, targeted landscape ecological planning suggestions were proposed, including ecological land protection, soil and water conservation, land development and building land control, ecological restoration projects, green space and landscape pattern optimization construction.
