“…Our results showed that most of the highly and moderately suitable areas were characterized with low elevation and gentle slope. The results indicated that topographic factors played a critical role in the land suitability analysis, which agrees with studies conducted at other mining sites [14]. The cells in the eastern and northern parts of the mining site were highly suitable for developed land since they were close to roads and city centers.…”

Abstract:Restoration of the degraded ecosystem is a global priority for achieving sustainable development. Although increasing ecosystem service is an important goal of ecological restoration, it is rarely used to inform mine reclamation. This study proposed a reclamation strategy that incorporated land suitability analysis and ecosystem service evaluation for a mining site in Liaoning Province, China. We assessed the land suitability for three reclamation alternatives and identified suitable land uses for each location by comparing their suitability levels. For areas that were suitable for multiple land uses with the same suitability level, the future land uses cannot be identified by land suitability analysis alone, and we employed ecosystem services evaluation to determine the optimal reclamation strategy. The results showed that forest could be restored throughout the entire mining site, agricultural land were most suitable in the western and southern parts, and developed land were in northern parts that were closer to roads and city centers. Our study showed that a large mining site can be reclaimed to different land uses and provided a practical framework for integrating ecosystem services into mine reclamation.

“…This water can be very acidic and laden with high concentrations of toxic heavy metals posing threats to the environment. Mining activities also cause health problems in the local communities and among wildlife by exposing them to mining waste in air, water and soil [24,[34][35][36][37][38]. The large-scale mining in the Qin-Ba mountainous area is posing direct and indirect threats to the local ecosystem [39,40].…”

Abstract:The Qin-Ba Ecological Functional Zone is a component of China's ecological security pattern designed to protect the regional ecosystem and maintain biodiversity. However, due to the impact of mining and urban encroachment, the plight of a sustainable ecosystem in the Qin-Ba mountainous area is deteriorating. This paper has used a remote sensing and geographic information system (GIS) to examine the impacts of mining and urban encroachment on the environment in the Qin-Ba mountainous area. The results indicate that the total mined area in 2013 was 22 km 2 and is predicted to escalate. Results also show that the ecosystems in Fengxian County, Shaanxi Province and Baokang County, Hubei Province were most severely affected by mining. Urbanization in the Qin-Ba mountainous area has seen an increase of 85.58 km 2 in urban land use from 2010 to 2013. In addition, infrastructure development including airport construction, tourism resorts and real estate development in the Qin-Ba mountainous area has intensified environmental and biodiversity disturbances since large areas of forest have been cleared. Our results should provide insight and assistance to city planners and government officials in making informed decisions.

“…Since the 1970s, Geographical Information Technology has promoted the development of land suitability evaluation [8,9,[14][15][16][17][18][19]. With advances in data collection and processing technology, land suitability evaluation has been gradually applied in various fields, such as crop suitability evaluation [20][21][22][23][24], landscape planning [25,26], waste management planning [27][28][29], environmental impact evaluation [30], land restoration [31], and urban sustainable development [32][33][34]. While few studies have considered the impact of policy orientation or development pattern on suitability evaluation, more attempts need to be made to evaluate land suitability in different scenarios.…”

With the acceleration of urbanization and industrialization, regional development is becoming increasingly disordered. Thus, how to balance economic development and ecological protection is a key question. To comprehensively evaluate land development suitability, an evaluation index system for construction land and farmland suitability was established in this study based on natural and social-economic information. After selecting an island in China as the main case study in this work, the reference method was applied in grading and value assigning for all indices. In addition, the analytic hierarchy process and expert evaluation method were used to determine the index weighting. After scenario analysis was adopted in the study to analyze the impact of the policy orientation on the suitability evaluation, we finally evaluated the landscape ecological quality of different scenarios. Results showed the landscape ecological quality of a coordinated development scenario was the highest. The results indicated that coordinated development which takes the ecological protection and urban development into account may be a better choice for land planning.
