    The Irtysh River Basin refers to a water conservation area and a vital ecological barrier in Xinjiang and also partially in Central Asia. Here, the technical solution for the ecological protection and the restoration of the Mountains-Rivers-Forests-Farmlands-Lakes-Grasslands system (MRFFLGs) pilot project in the Irtysh River Basin is refined, by complying with the core concept, i.e., “mountains, rivers, forests, farmlands, lakes and grasslands are a community of life”. The solution stresses the specific characteristics of ecologically protecting and restoring MRFFLGs in the Irtysh River Basin, which aim to reduce ecological water use, soil erosion, forest and grassland degradation, the ecological destruction of mines, water environment pollution and other issues. With overall protection, system restoration, district policy, and problem orientation as the overarching ideas, 162 sub-items of 44 major items with seven categories have been designed and implemented in the project. In addition, some highlights of the management experience that are worth promoting when the pilot project is being implemented are also summarized (e.g., the use of laws to solve historical problems, scientific argumentation and third-party evaluation, proactive guidance for the engagement of people, modern information technology support, and integration with local sustainable development). Lastly, four policy suggestions are proposed: (1) Building a model of systematic protection and restoration by using basins as the basic geographic unit; (2) Establishing and optimizing key weak links of systems and mechanisms; (3) Focusing on remedying the shortcomings of regional talents, technology and capital; and (4) Promoting the MRFFLGs project to integrate “industry, city, people, and tourism” for carrying out a large-scale system project.

    Altay Prefecture plays a vital role as an ecological barrier in Northwest China. Studying the ecosystem service value is of great significance for promoting regional green high-quality development and maintaining ecological security. Based on Global ESA land cover data from 2000 to 2015, the trade-off and synergy relationships and driving force factors between ecosystem services in Altay Prefecture were analyzed in this study. The analysis produced four main results. (1) The ecosystem service value in Altay Prefecture continued to increase from 113.521Ⅹ109 yuan in 2000 to 115.777Ⅹ109 yuan in 2015, for an increase of about 1.98%. (2) The distribution of ecosystem service value had obvious spatial agglomeration characteristics, with hot spot areas mainly concentrated in the "two rivers and one lake" and the mountainous areas in the northwest, while the cold spot areas were mainly the forest and grass-covered areas in the northern mountainous areas and within Jimunai County. (3) The trade-off and synergy relationship among ecosystem services was mainly synergistic, with a total of 77.78% of ecosystem service relative relationships showing a significant positive correlation at the 0.01 level. (4) Economic factors and industrial structure are important factors affecting ecosystem service value in Altay Prefecture. Ecosystem service value is positively correlated with per capita GDP and the output value of the tertiary industry, but negatively correlated with the output value of the secondary industry.

    Research on Ecological Protection and Restoration Measures in Altay Region based on the Coupling Perspective of the Mountains-Rivers-Forests-Farmlands-Lakes-Grasslands System

    The adoption of both Nature-based Solutions (NbS) and a system perspective is a hot issue and an area in which there is much room for improvement in ecological protection and restoration. The study takes Altay region as an example, an area located in Xinjiang, China, which is an important ecological corridor of the national key functional area and the core area of the Belt and Road but has a fragile ecological environment and needs much enhancement in ecological protection and restoration. Guided by the concept of “mountains-rivers-forests- farmlands-lakes-grasslands (MRFFLG) system is a life community”, the coupling relationship of the various MRFFLG elements, the main ecological environmental problems and the integrated countermeasures for protection and restoration in Altay region have been analyzed in this study. The study shows that Altay region has a typical meta-ecosystem of mountain, oasis, and desert, and the connections by rivers and lakes make the ecosystem links within the region much closer. The interweaving of resource-environmental-ecological issues of the aquatic ecosystem, degradation of the quality of terrestrial ecosystems such as forests, grasslands and farmlands, the increased ecosystem fragmentation and ecological risks are the major ecological environmental issues in this region. This study takes the improvement of the ecosystem health and function in Altay region as the core goal of regional ecological protection and restoration. First, we establish a zoning governance pattern from the perspective of ecosystem integrity; second, we design governance strategies for different zones with the goal of synergistic improvements in the ecosystem functions; and finally, we clarify the key engineering tasks in different zones from the perspective of ecosystem services. Ecological conservation and restoration of the MRFFLG system is a prime example of the application and development of NbS in China. This paper constructs an analytical framework for identifying regional life communities, diagnosing ecological protection and restoration of zoning problems, and proposing classified solutions for ecological protection tasks for the protection of the MRFFLG system. This research will enrich the theory and technology for the protection and restoration of MRFFLG systems, and provide guidance for the practice of ecological protection and restoration in Altay region.
