New Thinking on Desert Ecosystem Health Assessment
Ecosystem health serves as a benchmark for assessing the stability,sustainability,and vitality of an ecosystem.When the ecosystem health assessment system,primarily designed for forest,grassland,and wetland ecosystems,with a significant proportion of biodiversity as the main indicator,is directly applied to desert ecosystems,it often results in misinterpretations.In large-scale assessments of ecosystem health,desert areas are often found to be in a state of sub-optimal health or even unhealthy.This paper delves into the significance of assessing the health of desert ecosystems,defines the essence of desert ecosystem health,enumerates both positive and negative impacts of human activities on desert ecosystem health,and introduces a novel method for desert ecosystem health assessment based on reference systems of native deserts in various geological periods,offers a scientific foundation for the development of a more rational and scientific index system and method to assess desert ecosystem health in the future,and provides fresh perspectives for the effective implementation of comprehensive measures against desertification and the ecological development associated with the Great Green Wall in the new period.
