Abstract:

Vegetation restoration is fundamental to ecological restoration. A systematic analysis of the spatial mismatch between the Grain for Green Project intensity and vegetation restoration is the basis of scientific ecological protection and restoration policies. Based on the relative difference between the realization degree of vegetation restoration potential and the Grain for Green Project intensity, this study analyzed the spatio-temporal variation characteristics of the spatial mismatch pattern of vegetation restoration on the Loess Plateau, and explored its influencing factors by using geographical weighted regression. The results showed that: (1) The effect of vegetation restoration on the Loess Plateau had continuously improved from 2000 to 2022, with the overall realization degree of vegetation restoration potential exceeding 0.75 in 2022. The theoretical maximum value of vegetation restoration potential in southern Qinghai and western Shanxi exceeded 0.60, but the potential realization degree was lower than 0.65, making these areas key for future vegetation restoration. (2) The spatial mismatch index of the Grain for Green Project intensity and vegetation restoration was generally higher than 0.70, indicating a serious spatial mismatch, and this mismatch was gradually spreading throughout the region. (3) Rural population pressure and agricultural industrial structure were the primary factors contributing to the spatial mismatch between the Grain for Green Project intensity and vegetation restoration on the Loess Plateau, which brings challenges to the successful achievement of the ecological objectives of the Grain for Green Project. In the future, the Loess Plateau should focus on optimizing the agricultural industrial structure and increasing the intensification of urban construction land, so as to alleviate the spatial mismatch between the Grain for Green Project intensity and vegetation restoration.
