英文摘要 | The oasis-desert ecotone as a transitional zone is sensitive and vulnerable to hydro-climatic changes and anthropogenic activities in maintaining oasis stability and combating desertification. The normalized difference vegetation index (NDVI) is an important indicator for evaluating the desert vegetation restoration status. However, it is difficult to quantify individual and interactive impacts of hydro-climatic changes and anthropogenic activities on NDVI in the oasis-desert ecotone. This paper introduces the hydro-climate elasticity and geographical detector approach to assess the influences of hydro-climate changes and human activities on NDVI in Qira oasis-desert ecotone, Northwest China during 2000-2019. Results show that the climatic elasticities of NDVI reflect that the NDVI is more sensitive to precipitation (0.318) than to temperature (0.290), while the NDVI becomes more sensitive to variation in soil moisture content (0.219) than that in the groundwater table (0.150) in hydrological elasticities. The land-use change caused by human activities results in a decrease of NDVI, accounting for 90% of NDVI reduction. The human activities indicate the strongest influence on NDVI. The nonparametric elasticity estimator proposed is illustrated good agreement with the spatiotemporal synchronism of NDVI to hydro-climatic changes. The interaction analysis of geographical detector reveals that the interaction among influencing factors has a bivariate enhancement relationship and a nonlinear enhancement effect on NDVI. This study contributes to clarifying the individual influencing and interactive relationships of NDVI to hydro-climatic factors and human activities, and assist land restoration practitioners to evaluate the desert vegetation restoration status under current and future hydro-climatic changes in arid regions. |
