“…The loess hilly region is a key area for large-scale ecological restoration in China. During the process of ecological protection and restoration, it is urgent to explore the internal mechanism of ecosystems, follow the succession law of the natural ecosystem, unleash the self-healing ability of nature, avoid excessive human intervention in the ecosystem and take measures such as protection and restoration, nature and labor, biology and engineering to form the basis of strategies to preserve the natural advantages of ecosystems and promote integrated ecological protection and restoration [4].…”

The ecological environment in loess hilly regions is fragile, and the contradiction between the development of human society and ecological environment protection is becoming more and more prominent with the intensification of human interference. In order to give full play to the role of ecosystem adaptation in ecological restoration, this study seeks natural conditions that are suitable for the stable existence of ecosystems in the Wanhuigou catchment using the reference ecosystem method and uses these conditions as constraints of the GeoSOS-FLUS model for multi-scenario simulation. Based on ecosystem service value and ecological compensation mechanisms, the comprehensive benefits of different scenarios are compared, and economic development is taken into account while ensuring that ecological protection remains a priority. The results show the following: (1) The unstable ecosystems concentrated on a gentle slope (5–15°) at altitudes of 1201–1379 m, 1201–1594 m, 1379–1715 m and 1715–1856 m are suitable for restoration to farmland, shrub, grassland and forest ecosystems, respectively, and the change characteristics of soil and vegetation communities also verify the above conclusions. (2) The scenario of agricultural development from 2020 to 2030 and the early stages from 2030 to 2050 is the best among the three scenarios, while the scenario of ecological protection is the best in the middle and late stages of 2030–2050. Formulating relevant policies and ecological protection measures according to the scenario of ecological protection is more conducive to promoting the harmonious coexistence of humans and nature. (3) Under the scenario of ecological protection, the unstable ecosystem distributed along the gentle slope (5–15°) of 1379–1483 m and 1483–1594 m achieves the most significant improvement in ecosystem service value by focusing on and giving priority to the restoration of natural conditions that are suitable for the stable existence of ecosystems. This study provides ideas and references for the formation of ecosystem restoration and development strategies for small watersheds in loess hilly regions, and it is of great significance for the promotion of a harmonious coexistence between humans and nature.

“…It is mostly found in the provinces of Gansu, Shaanxi, Ningxia, Shanxi, Henan and Qinghai, along the middle and upper reaches of the Yellow River [2], which is an extremely fragile ecological area [3]. The Loess Plateau's ecological environment problem of soil erosion [4] is a typical example of this weak ecological environment.…”

Ecological Restoration Strategies for the Topography of Loess Plateau Based on Adaptive Ecological Sensitivity Evaluation: A Case Study in Lanzhou, China

Existing studies related to ecological sensitivity evaluation are comparatively mature; however, few approaches are concerned with distinctive topographical conditions that enable response to specific environmental restoration requirements. In this paper, an adaptive ecological sensitivity evaluation framework is established according to a representative plateau topography (i.e., the Loess Plateau region) via a case study of Gaolan County, China. Through the process of factor selection, index system construction, formula adaption, factor weight determination by analytic hierarchy process (AHP) as well as the support of RS and GIS technology, the ecological sensitivity of the research region has been evaluated and analyzed in combination with land use types and typical gully problems. The results show that high sensitivity areas account for 11.16 percent of the total area in the research region and a tendency for fragmentation in spatial distribution. Forest lands with steep slopes in gullies` upstream have the highest ecological sensitivity, the proportion of forest and garden land dominated by trees in the highest sensitivity area is around 80 percent. Evidence-based ecological restoration strategies are proposed in terms of the topography of Loess Plateau. This study shows possibilities to adapt existing sensitivity evaluation model for medium-scaled specific topography problems and provides useful clues as a basis for knowledge acquisition that can feed into spatial design, planning and restoration processes.
