生态系统退化是多种因素相互作用的结果，包括气候变化和人类活动。因此，我们必须了解导致生态退化的关键因素，并确定其对生态系统变化的影响，然后才能进行生态恢复。为了验证这一假设，我们提出了一项措施，我们称之为“有针对性的措施，以控制生态恢复”。该方法计算了生态恢复过程中各关键因子和控制措施对生态系统变化的贡献，通过识别关键因子，帮助管理者根据这些因子设计有效的恢复策略。为了验证这种方法，我们在2000年至2016年期间在中国福建省长汀县的四个城镇进行了案例研究。虽然从1984年到1999年植被覆盖率下降了3.1%，但在2000年到2016年实施新措施的试验区，植被覆盖率和植被物种丰富度分别增加了94.8%和616.7%。这些比率分别是对照区的4.5和148.2倍。我们的新方法侧重于修复退化的生态系统，而不是创造新的生态系统。案例研究表明，了解生态系统动态可以帮助我们更有效地处理气候变化和人类活动的同时影响。
Ecosystem degradation is caused by interactions among multiple factors, including climate change and human activity. Therefore, we must understand the key factors that underlie ecological degradation and determine their impacts on ecosystem change before we can undertake ecological restoration. To test this hypothesis, we proposed a measure that we call “targeted measures to control ecological restoration”. This approach calculates the contribution of every key factor and control measure to ecosystem change during ecological restoration; by identifying the key factors, it helps managers to design an effective restoration strategy based on those factors. To test this approach, we performed a case study from 2000 to 2016 in four towns of Changting County, Fujian Province, China. Although the vegetation cover decreased by 3.1% from 1984 to 1999, vegetation cover and vegetation species richness increased by 94.8 and 616.7%, respectively, in the test areas where new measures were implemented from 2000 to 2016. These rates were 4.5 and 148.2 times those in the control area, respectively. Our new approach focuses on repairing degraded ecosystems rather than creating new ones. The case study suggests that understanding ecosystem dynamics can help us deal more effectively with the simultaneous effects of climate change and human activity.
