Ecological Governance

The Chinese government is committed to sustainability governance to alleviate the shortage of energy and the imbalance between ecological environment and economic development. This paper evaluates and analyzes the sustainability governance performance of China. A bootstrap data envelopment analysis (DEA) is proposed to evaluate sustainability governance performance of 30 provinces based on ecological efficiency in China from 1998 to 2015. The results indicate that the ecological efficiency of China significantly improved as a whole, which is related to the decline in sulfur dioxide emissions. Among these provinces, Jiangsu, Liaoning, and Inner Mongolia exhibited the highest values, while Gansu, Chongqing, and Sichuan had the lowest values. The 30 provinces were divided into four sub-areas. The average ecological efficiency of the eastern area was the highest, followed by the northeast area. Compared to the east area, northeast area, and central area, we find that west area obviously falls behind. As such, the results provide helpful guidance to improve ecological governance performance.

During the exploitation and utilization of the mineral resources, varieties of pollutants have been produced, which would impact the natural environment inevitably and bring many adverse effects to ecological environment and the human health. Its worth noting that the wastewater from copper mineral processing (WCMP) is one of the main source of mine environmental pollution. The WCMP is characterized by large quantity and containing large numbers of suspended solids, residual flotation reagents and heavy metals, etc. Wastewater can be discharged and realized reuse only after effective treatment. Recently, natural sedimentation, neutralization, flocculation, oxidation and other treatment techniques by wastes are the commonly used methods to treat the mineral processing wastewater.

Mercury in coals is one of the important sources of atmospheric mercury, which is potentially harmful to the ecological environment. Based on the data of 970 coal samples, the concentration, spatial distribution and occurrence of mercury in Chinese coals were analyzed. The main conclusions are as follows: The distribution of mercury concentration in Chinese coalfields is uneven; medium and high mercury coals are mainly distributed in southwest China and eastern Inner Mongolia. The mercury concentrations in various coal-forming periods are as follows: K (0.320 mg/kg) > P2 (0.220 mg/kg) > C3 (0.179 mg/kg) > J (0.177 mg/kg) > D (0.165 mg/kg) > P1 (0.136 mg/kg) > C1 (0.090 mg/kg) > E (0.086 mg/kg) > T3 (0.066 mg/kg). The mercury concentrations in different coal ranks are as follows: Lignite (0.164 mg/kg), long flame coal (0.078 mg/kg), non-caking coal (0.256 mg/kg), weakly caking coal (0.086 mg/kg), gas coal (0.151 mg/kg), fat coal (0.122 mg/kg), coking coal (0.171 mg/kg), lean coal (0.393 mg/kg), meagre coal (0.161 mg/kg), anthracite (0.160 mg/kg). Sulfide bound state is the main form of mercury in coals, and pyrite is the main occurrence medium.

The Impact

Ordos is the most abundant coal resource city in Inner Mongolia. Its coal resources account for one half of Inner Mongolia's coal resources and one sixth of China's total coal reserves. Abundant coal resources have laid the foundation for Ordos become today’s resource-based city. In 2003, Inner Mongolia issued “the guiding opinions on accelerating the development of key coal enterprises” (hereinafter referred to as “policy”), supporting the development of coal enterprises and providing policy conditions for the rapid economic development of Ordos. However, with the rapid development of economy, the rural-urban income disparity is also getting bigger in Ordos. Based on panel data from 1999 to 2012 and use the DID analysis of “quasi-natural experiment”, the paper finds that the policy has increased the rural-urban income disparity. The policy increases the rural-urban income disparity by promoting GDP growth. Therefore, the role of the policy system in the economic development of a region cannot be ignored. The government supports the development of local resource-based industries and also increase support for the development of upstream and downstream industries. Under the guidance of policy, the mineral resources income should be transformed reasonably. Government should invest the proceeds of mineral resources in material capital and human capital. Government also should invest the proceeds of mineral resources in external industries and projects that require large initial capital or long construction cycles, such as those essential infrastructure sectors: education, health, transportation and energy. In this way, the integration of urban and rural development will be realized and the rural-urban income disparity will be reduced.

In the majority of farming-pastoral areas, Inner Mongolia, grassland slope was reclaimed recent years due to the increase of population. The resulting deterioration of ecological environment problem is becoming more and more serious. In 2012, the effect of reclamation on erosion, vegetation and soil characteristics were researched in Saiwusu of Damao County, Inner Mongolia. Results show: 1. Severe wind erosion in spring, also severe water erosion in summer were on the slopping field. 2. After cultivation, annual herb such as Salsols collina, Corispermum declinatum, Chenopodum aristatum, Artimisia annua et al. grew vigorously, however perennial herb such as Stipa krylovii, Leymus chinensis and Agropyron cristatum were inhibited. 3. Soil nutrient sharp declined due to the erosion and harvest. In short, the grassland which converted to slopping field increases more than 5 times of soil erosion, soil fertility drops 30%, and vegetation changed completely after 1 year; 4 years later, soil fertility drops 50%, vegetation becomes sparse, soil water and fertility is poor, crop yield is low, the slopping field is not fit to continue farming, large abandoned.
