    Assessment of ecological asset quality and its drivers in Agro-pastoral Ecotone of China by Wenmin Liu, Zhiyuan Cheng, Jie Li, Guang Li, Ninghui Pan

    Published 2025-01-01
    “…The distribution pattern of the ecological assets was also obvious, showing a distribution pattern of high in the northeast and low in the middle. (2) The effects of altitude and latitude/longitude on the quality of ecological assets in the study area were mainly characterized by a decreasing trend in the quality of ecological assets with decreasing altitude from west to east, and a decreasing and then increasing trend in the quality of ecological assets with increasing altitude from south to north. (3) The quality of ecological assets has a complex correlation with climate and socio-economic factors, among which, temperature and precipitation are significantly positively correlated in the middle altitude (785–2968 m) and low altitude northwest; socio-economic factors are significantly positively correlated with large and medium-sized agricultural tractors, agricultural, forestry, animal husbandry and fishery population and rural population in the high altitude area, significantly positively correlated with GDP of the primary industry in the middle altitude area, and significantly positively correlated with agricultural population and animal husbandry and fishery population in the low altitude area. (4) The construction of a comprehensive assessment system that introduces soil and terrain indices mainly shows an increase in the proportion of medium and low grades of ecological asset quality and a decrease in the proportion of excellent, good, and poor grades, compared with the quality of ecological assets using only the perpendicular index as the assessment system. …”
