在过去的十年中，生态恢复实践在全球范围内得到了推广。然而，生态恢复的有效性取决于各种自然和社会经济因素的复杂相互作用，对此科学认识有限，因此提供了一个重要的研究前沿。以黄土高原为例，分析了区域尺度植被恢复与城市化进程的关系。这一地区经历了快速的城市化和大量的植被恢复活动。城市化和植被恢复可被视为环境保护活动范围内的极端情况。城市化和植被恢复之间的三个独立的空间相关性分析确定，导致：1）在饱和的城市地区不显著的相关性; 2）在城市周边地区显着的负相关性;和3）在欠发达地区显着的正相关性。因此，城市化与植被恢复之间的关系是分阶段的。城市化对植被退化的影响有所改善，但尚未通过大规模植被恢复得到充分解决。无论是县或网格尺度，半城市化被认为是影响植被恢复的时间和空间的有效性的关键因素。因此，半城市化地区被视为改善城市发展和植被恢复耦合的优先事项。
Over that past decade, ecological restoration practices have expanded globally. However, the effectiveness of ecological restoration depends on the complex interactions of various natural and socioeconomic factors, about which there is limited scientific understanding and thus provides an important research frontier. This paper analyzed the relationship between regional scale vegetation restoration and the process of urbanization using the Loess Plateau of China as a case study. This region has experienced both rapid urbanization and a high number of vegetation restoration activities. Urbanization and vegetation restoration can be considered as extremes on the spectrum of environment preservation activities. Three separate spatial correlation analyses between urbanization and vegetation restoration were identified, resulting in: 1) insignificant correlations in saturated urban areas; 2) significant negative correlations in peri-urban areas; and 3) significant positive correlations in undeveloped areas. The relationship between urbanization and vegetation restoration is thus stage-dependent. Impacts of urbanization on vegetation degradation has improved but has not been fully addressed by large scale vegetation restoration. Regardless of whether the county or grid scale is used, peri-urbanization was found to be the critical factor affecting the effectiveness of vegetation restoration over both time and space. Therefore, periurbanized areas are viewed as priorities for improving the coupling of urban development and vegetation restoration.
