The Zhundong coalfield in Xinjiang, China, is rich in resources and has great significance to the development of the Xinjiang region, but its local ecological environment is fragile and its climate is particularly dry, so mining is very likely to introduce a series of ecological risks; there is an urgent need for us to provide scientific and feasible guidance for the conservation and development of coal resources in this region. Therefore, this paper is based on the land-use-type data concerning the Zhundong Economic and Technological Development Zone from 2000 to 2020, exploring the land use change characteristics in the Zhundong area during these 20 years and calculating the ecological risk index of each risky district according to an ecological risk index model. Afterward, this article uses kriging interpolation to carry out a risk classification analysis to explore changes in ecological risk in the Zhundong area during the last 20 years and to put forward ecological risk partition and control measures for areas of different levels of risk. Our research shows the following features: (1) The land use type in the Zhundong area changed obviously from 2000 to 2020, in which unused land has always occupied most of the area of the Zhundong coalfield. Grassland was the land use type with the greatest area transferred, 211,412.35 hm2, accounting for 68.11% of the total transferred area, and it was mainly converted into unused and construction land. (2) In the last 20 years, the Zhundong coalfield has been dominated by higher-risk and high-risk areas, with obvious changes in the distribution of ecological risk levels. The low-risk, medium-risk, and higher-risk areas in the research zone have decreased and then increased; the lower-risk area has declined yearly, and the high-risk area has increased and then declined. Furthermore, overall, the ecological environment has transformed toward good condition. (3) High-risk and higher-risk areas still account for most of the research zone, and there is an urgent need for scientific and feasible programs to carry out ecological restoration in areas with different ecological risk levels to avoid further deterioration of the local environment.

“…It gradually developed into a regional ecological risk assessment of the likelihood of adverse impacts and the degree of potential hazards caused by various risk factors such as environmental pollution, anthropogenic coercion, or natural disasters in different types of ecosystems within the region [13]. With the combination of landscape ecology theory and ecological risk assessments, landscape ecological risk assessments have become a hot topic in the field of regional ecological risk assessments [14]. The main method used to achieve this includes two aspects: one involves constructing ecological risk models based on risk sources and sinks.…”

It is highly valuable to analyze and assess the landscape ecological risk of nature reserves to prevent and resolve ecological risks, as well as to effectively protect and maintain the sustainable development of nature reserves. Taking the forest landscape of the Lushan National Nature Reserve as its study object, this study performed grid processing for the nature reserve and classified forest landscape types using the Forest Resource Inventory Database in 2019. A landscape ecological index model was constructed to evaluate the ecological risk. Global and local Moran index values were used to reveal the autocorrelations for ecological risk. The geodetector method was used to comprehensively analyze the effects of natural and human factors on ecological risk. The results showed that, in general, the ecological risk level of the nature reserve was relatively low, as the proportion of the lowest-, lower-, and medium-risk areas to the total forestry land area accounted for 91.03%. The ecological risk ranking of each functional zone, from high to low, was in the order of the experimental zone, the buffer zone, and the core zone. The ecological risk levels of different forest landscape types were closely related to their area, spatial distribution, and succession stage, as well as human factors, such as the proximity to roads and settlements, etc. The forest landscape with the highest ecological risk was the Cunninghamia lanceolata (Lamb.) Hook. forest, and the forest landscape with the lowest ecological risk was other forestry land. Ecological risk had a positive spatial correlation and tended to be aggregated in space, demonstrating coupling with the proximity to roads and settlements. The ecological risk was affected by both human and natural factors, among which human factors played a dominant role. The proximity to roads and settlements, the relative humidity, and the temperature were the main driving factors. The interaction of pairwise factors had a stronger influence than that of single factors. Therefore, controlling the intensity of human activities and enhancing the coordination between humans and nature are beneficial for alleviating the ecological risks in the forest landscapes of nature reserves.

“…With the landscape ecological risk assessment, which is based on land-use change and is becoming a research hotspot, researchers worldwide have furthered the research on the topic [23,24]. Most research areas are concentrated in key risk control regions, such as urban [25] and administrative [26] areas, watersheds [27], industrial and mining areas [28] and nature reserves [29]; however, landscape ecological risk assessment around lakeside areas needs to be further developed.…”

As an important ecological ecotone of water and land ecosystems, the lakeside is characterized by a variety ecosystem services and high vulnerability. Forest land is important in resolving the ecological risks of the lakeside area and building its ecological base. It is important to explore the effect of change in forest land on landscape ecological risk in the lakeside area, alleviate the contradiction between ecological protection and construction and development in the area, and realize sustainable development. The present study attempted to explore the spatial and temporal evolutionary features of forest land in the Erhai rim region from 2000 to 2020 using bivariate spatial autocorrelation and multi-scale geographical weighted regression (MGWR) models. The following are the findings of this investigation of the 2000–2020 period: (1) the forest land area in the region generally decreased, first increasing and then decreasing, and was mainly occupied by cultivated land and artificial surfaces; (2) the total landscape ecological risk in the region presented an upward trend, and medium- and higher-risk areas were the main risk areas, with the latter increasing; (3) the impact of forest land expansion and contraction intensity on landscape ecological risk exhibited spatial and temporal heterogeneity. The main forms of forest land change at different stages differed, and the impacts on landscape ecological risk were also different. Reasonable forest land expansion can effectively alleviate the growth in landscape ecological risk, whereas the shrinkage of forest land would aggravate the landscape ecological risk in the Erhai rim region. Moreover, the findings can offer reference for the exploration of ecological protection and coordinated optimization of economic development in Erhai Lake.
