“…The Pingshuo's mining area is equipped with top-notch mining and production technology equipment, such as heavy trucks and power shovels (see Figure 7c). At the same time, on the basis of the advanced technical equipment, the Pingshuo Coal Co., Ltd. actively implements the modernization of information mining enterprise management; therefore, the Pingshuo Coal Co., Ltd. has become the largest open-pit mine in China, also known as one of the mines with the most sense of science and technology in China [20]. The Pingshuo Coal Co., Ltd. is known as "the most mechanized mine in China" due to its active cooperation with the United States at the end of the 20th century and the introduction of many large and advanced mining and production equipment.…”

This paper (Part II), right after the Part I, also as an information article, introduces the recent progress of “green mine construction” in China. China is a big country in resource exploitation, but there are serious problems such as hidden danger, environmental pollution and resource waste in the exploitation of mineral resources in China. Therefore, the promotion of “green” mining technology, the implementation of “green mine construction” and the promotion of small- and medium-sized mines to green non-waste mining mode transformation and upgrading are crucial measures on the road of China’s mining development, with very important practical significance. Therefore, this information paper of our Chinese mining research mainly reviews the key progress in the construction and development of green mines and introduces four typical green mine examples in China: (1) the mine with the best green environment in China: Jinhui Mining Co., Ltd., Jiuquan, Gansu Province; (2) the most advanced mine in China: Jinchuan Group Company, Jinchang, Gansu Province; (3) the oldest green mine in China: the Suichang gold mine, Lishui, Zhejiang Province; and (4) the most mechanized mine in China: the Pingshuo Coal Co., Ltd., Shuozhou, Shanxi Province. In the abstract, we claim that Part II serves as a guide to begin a conversation and to encourage experts and scholars to engage in the research of this field.

“…As show in Figure 1, the study area is located in the Pinglu District, Shuozhou City, Shanxi Province, between 111 • 52 -112 • 41 E and 39 • 21 -39 • 58 N. The area is 67.9 km wide from east to west and 69.5 km long from northwest to southeast, with an area of 517.48 km 2 . The region has a typical arid/semi-arid temperate continental monsoon climate with average annual precipitation of 428.2-449.0 mm and evaporation of 1786.6-2598.0 mm, resulting in drought and rain erosion [20]. The zonal soil is a transition between chestnut soil and chestnut cinnamon soil with low organic matter content and inferior structure.…”

“…The zonal soil is a transition between chestnut soil and chestnut cinnamon soil with low organic matter content and inferior structure. Besides the harsh natural conditions, disasters such as landslides and collapses are easily caused by the production process due to the impact of the slope and other environmental factors, as well as mining earthquakes caused by blasting, exploiting, and other mining activities [20]. Furthermore, the negative effects of mining operations, such as soil erosion, vegetation degradation, and surface water pollution [22], can spread rapidly in the area.…”

“…The Pingshuo open-cast mining area is located in a typical arid/semi-arid ecologically fragile region [19] belonging to the Jinbei coal base area in western China [13]. In an area such as this, mining activities will inevitably affect the landscape pattern, even disastrously in some cases [20]. Ecological sources with strong ecological functions must be identified and protected to ensure the supply capacity of the ecosystem service.…”

Open-cast coal mining in China has developed rapidly due to its obvious advantages over underground mining. However, it may have negative ecological effects, such as biodiversity loss, water shortage, and soil erosion. Identifying and protecting the key areas with high importance for ecological sustainability are great challenges. The construction of an ecological security pattern (ESP) can improve landscape connectivity and reduce the fragmentation of ecological patches. Thus, it can be seen as an effective measure to protect regional ecological sustainability. In this study, taking the Pingshuo open-cast mining area as a case study area, ecological sources are identified through ecosystem structure and function, and corridors are extracted by constructing an ecological resistance surface, thus forming a valid ecological network. The results show that in 2018, the ESP in the study area included 11 sources with an area of 147.74 km2 and 17 corridors with a length of 92.11 km. Specifically, the ecological sources are mainly distributed in Taocun Township, Jingping Township, and Xiangyangbao Township. Among these 11 sources, sources 7 and 8 are reclaimed waste dump land, meaning that the land reclamation work in Pingshuo greatly promotes connectivity. Furthermore, dump 1 can be restored in the future by constructing three new corridors, which will greatly improve the landscape connectivity of Yuling Township. Overall, this study not only provides an effective framework for constructing and optimizing ESPs in ecologically fragile coal mining areas, but it also adds new insights to the concept of land reclamation in these areas.

“…In 2003, Chen et al [17,18] introduced the source-sink theory into landscape ecology, constructed the source-sink landscape theory, and integrated landscape pattern research and ecological process research. Since then, the source-sink landscape theory has been applied to nonpoint source pollution control [19], ecological risk assessment [20], soil erosion control [21], ecological security network construction [22], functional regionalization of nature reserves [23], suitability evaluation of land use [24], etc. The source-sink landscape theory integrates landscape type, area, and spatial location and the impact of the landscape on ecological processes better than other theories.…”

Promoting the preservation and appreciation of ecosystem services is an important value guide for land use optimization. In this research, Fengdu County in the Three Gorges Reservoir Area was selected as the focus of a case study. From the perspective of the source and sink landscape of ecosystem services, a MOP model and FLUS model were used to optimize the areas of various land use types and the spatial configurations of those land use types in the study area in 2035 under a strict ecological constraint (SEC) scenario, a moderate ecological constraint (MEC) scenario, and a relaxed ecological constraint (REC) scenario. We also superimposed and adjusted the results of land use optimization under the three ecological constraint scenarios, and obtained land use regionalization results that integrated multiple scenarios. The results indicated that (1) there were large differences in the areas and spatial distributions of the source and sink landscapes under the three scenarios. Under the SEC scenario, the important source landscapes (ISLs), common source landscapes (CSLs), and sink landscapes (SLs) areas covered 1676.62 km2, 1190.43 km2, and 33.81 km2, respectively. A large area of the CSLs and a small area of the SLs were transformed into ISLs area, and the degree of fragmentation of the landscape was low. Under the MEC scenario, the ISLs, CSLs, and SLs areas covered 1609.22 km2, 1241.60 km2, and 49.74 km2, respectively. The development of the source landscapes and sink landscapes was similar, and the degree of fragmentation was moderate. Under the REC scenario, the ISLs, CSLs, and SLs areas covered 1603.96 km2, 1243.32 km2, and 53.58 km2, respectively. A large area of CSLs was transformed into SLs area, and the degree of fragmentation was high. (2) Fengdu County was divided into seven types of areas: ecological conservation area; agricultural production area; construction optimization area; construction-ecological area; ecological-agricultural area; agricultural-construction area; and integrated development area. The results of this study can provide references for the territorial spatial planning and management of ecological barrier zones.
