当代生态工程更加注重生态恢复与农村发展的协调。中国实施了世界上规模最大的退耕还绿色工程，在西南和西北地区取得了显著成效。本文以延安市为例，揭示了植被恢复的时空过程，阐释了农村社会经济结构调整对生态恢复的推动作用。结果表明，延安市植被恢复呈现出一个连续的过程和整体的格局，2000 - 2015年91.6%的面积NDVI指数增加，但退耕还草仅占15.68%。NDVI的增长与农村常住人口的变化、农业产值比重的变化以及区域城镇化水平的变化密切相关，这些变化标志着农村结构的调整。农村经济结构调整、社会形态重塑和空间布局调整，降低了对资源环境的依赖程度，改善了人地关系，促进了持续、稳定、全面的生态恢复。除了支持生态补偿和生态旅游产业外，还应采取更加积极和全面的措施，促进农村结构调整，使生态修复更加稳定和可持续。
The contemporary ecological projects paid more attention to the coordination between ecological restoration and rural development. China have launched the world’s largest Grain for Green Program and made significant achievements in this respect in south-west and north-west regions. This paper uses Yan’an as its case study location to bring the detailed spatiotemporal process of vegetation restoration to light and interpret the role of socioeconomic restructuring in rural areas as a mechanism for driving forward ecological restoration. The results showed that vegetation restoration in Yan’an has emerged as a continuous process and holistic pattern with 91.6% area NDVI index increasing from 2000 to 2015, but returned slope cropland directly account for only 15.68% of NDVI growth. The NDVI growth is closely related to change of rural resident population, proportion of agricultural output and regional urbanization level which signifying rural restructuring. Rural economic restructuring, social community reshaping and rural space readjustment have reduced the dependence of these areas on resources and environment, improved the man-land relationship, and spurred sustained, stable and holistic ecological restoration. In addition to supporting eco-compensation and ecotourism industries, more active and comprehensive measures should be adopted to promote rural restructuring and make ecological restoration more stable and sustainable.
