“…To some extent, agriculture and rural areas have contributed to the industry and cities development in the process of industrialization and urbanization, but great sacrifices have also been made [44]. As a result, a series of problems, such as the reduction of cultivated land, ecological destruction, environmental deterioration, and a widening gap between urban and rural areas, have appeared, which has restricted the development of the rural social economy and urban-rural integration [45][46][47]. The urban-rural income ratio is still expanding, and the gap between urban and rural areas is obvious.…”

Differentiation of Rural Development Driven by Natural Environment and Urbanization: A Case Study of Kashgar Region, Northwest China

With the socio-economic transformation, the recombination of regional development factors and the followed reconstruction of the rural development elements system have profoundly changed the rural landscape of the Kashgar region in Northwest China. The factors affecting the rural production and lifestyle interact with each other, shaping different types of rural development. Accordingly, basing on the main factors influencing the rural development ability and long-term development potential, the assessment indicator system of rural comprehensive development (RCD) was established to reveal the differentiation of rural development and identify the dominant factors affecting rural development. The principal component analysis method and the cluster analysis method was used to distinguish the different types. The results show that the high-level rural development areas are mainly concentrated in the center of the region, while the low-level areas are mainly distributed in the periphery, with significant spatial differentiation characteristics. We divided the rural development into three categories and 11 zones for which the basic natural conditions and external challenges are different. The categories reflect three possible results of rural development: grow, decline, and vanish, which is in the industrialization development stage. With the transformation of human society and the change of urban–rural relationship in its mode and content, the external economy, society, and changing environment has put pressures on rural areas. Therefore, according to different rural development types, it is necessary to take measures to strengthen the rural areas to cope with external environmental challenges.

“…To a certain extent, land-use types can reflect characteristics of different eco-environment and represent different eco-environment quality [8]. Therefore, scholars [33][34][35][36][37][38][39][40] proposed the valuation method for the eco-environmental quality owned by land-use types, which can realize the quantitative analysis of regional eco-environmental changes and spatial features. Some scholars [33,34,39] synthesized study results in the different regions to summarize the main ecological process and the value of ecosystem effects.…”

Have Changes to Unused Land in China Improved or Exacerbated Its Environmental Quality in the Past Three Decades?

et al. 2016

Abstract:Inappropriate land use has caused a series of environmental disasters such as floods and sand storms, and some of them involved unused land changes with highly localized distributions in arid and semi-arid regions with fragile ecosystems. As the third-rank category of first-level land use/cover in China, unused land (UL) is now playing an increasingly important role in protection of the natural environment and sustainable utilization of land resources. In this article, we assessed the effects on regional eco-environments employing a quantitative EL (ecological effect index) model, which can be used to evaluate and represent the contribution of UL changes to the eco-environmental quality. Results show that UL changes generally contributed to the deterioration of eco-environmental quality during the study period. Some major contributors to improving eco-environmental quality were transformation of sandy land and saline-alkali lands to grasslands, expansion of water bodies in UL areas, and reclamation of farmland in UL areas (except for marsh lands). In contrast, the main contributors to worsening eco-environmental quality were grassland degradation to UL (except marshes), reclamation of marsh areas, and shrinkage of water bodies to leave desert or saline-alkali land. Some suggestions are provided about UL management, utilization, and protection issues.

“…Because of the special geological formation of carbonate rock, the ecological degradation caused by carbonate rock mining is particularly serious. In recent years, studies have applied a variety of evaluation methods to determine the characteristics of the mine environmental degradation, which have been reviewed in detail (Liu et al, 2003;Si et al, 2010). In addition, studies of rocky desertification in carbonate rock areas have primarily focused on changes in the physical and chemical properties and biological species of the soils (Jiang et al, 2014).…”

Carbonate minerals are extensively distributed across China, and their special rock structures make them vulnerable to land damage through mining, leading to rocky desertification. Soil microorganisms play an important role in mineral weathering. However, little is known about the utilization of the mineral‐weathering microorganisms to alleviate the problem of rocky desertification in mines. In the present study, the mineral‐solubilizing bacterium NL‐11 was isolated from soil around weathered dolostones and identified as Bacillus thuringiensis based on the Biolog identification system and 16S rDNA sequence analysis. The mineral dissolution experiments revealed that inoculation with the live bacterium significantly increased the mineral sample dissolution via significantly enhancing Ca and Mg release, with increase values of 303·27 and 50·55 mg L−1 respectively, compared with that with the inactivated bacterium. Moreover, the acetic acid secreted by strain NL‐11 markedly decreased the size of particle diameter (quantified with a laser diffraction particle size analyser) through reducing pH value. The eroded traces were observed by scanning electron microscopy analysis, and the results further verified the erosional effects of this strain. In addition, this bacterium contributed to the establishment and proliferation of plants by providing nutrient elements, such as phosphorus (P) and potassium (K). Our study not only provided an efficient bacterial strain NL‐11 but also enriched the technologies to mitigate problems associated with ecological restorations of carbonate mines.
