Rural Residential Land

Rural residential land is the main space of a farmer’s life, rural culture, and social relations. Prior research of rural residential land has focused more on its evolvement in plain and traditional agricultural areas. Yet, there is no clear picture of rural residential land expansion, especially in ecologically fragile areas. This study analyzed the characteristics of rural residential land expansion based on 30 m spatial resolution land-use datasets of the Baota District of Yan’an City, Shannxi Province, and further explored the influencing factors and mechanisms of rural residential land expansion through binary logistic regression (BLR) modeling. Our findings indicated that the area of rural residential land in the Baota District increased by 116.16% during 1990–2015. More than 75% of the residential land expansion came from the occupation of cropland. Moreover, rural residential land expansion was heterogeneous in the rural regional system. The expansion scale, speed, and mode diversity of rural residential land decreased with the increased distance to urban built-up areas. Geographical conditions and resource endowments are the primary internal driving factors; urbanization and policy implementation are two major external driving forces. The authors suggest that the realization of regional sustainable development in ecologically fragile areas should strengthen urban–rural integration, focus on constructing central towns, and ensure ecological protection measures.

The demand for the development of eco-friendly, sustainable, and adaptable technologies for the disinfection of the environmental contaminants is increasing nowadays. Nano-bioremediation is one such technique that has made possible the use of biosynthetic nanoparticles for soil pollution remediation. It is an effective, efficient, and feasible method for revitalizing soil potential and rendering it pollution free. Pollutants present in soil are a great threat to soil biota, environment, and in fact human health. Nanomaterials exhibit the unique chemical and physical properties because of which they have always received attention in the growing era of bioremediation. Use of nanotechnology for bioremediation is one such technology as it focuses mainly on the interaction between the contaminants, the microorganisms, and the nanomaterials being used for both the positive (i.e., stimulating) and negative or toxic environmental effects. Thus, this chapter focuses on the need to recover the polluted soil and application of nano-remediation technology for restoring soil's cultivation capacity.

Groundwater is an important part of the human living space and supplies us with high-quality freshwater resources. However, the intrusion of any foreign matter into groundwater may cause groundwater pollution. Once this happens, clearing, control and remediation can be very difficult: not only does it need a lot of money, it is also technically challenging and time consuming. In view of current research on groundwater remediation in and out of China, we propose a package of groundwater pollution investigation, groundwater pollution remediation technology and groundwater pollution control processes with a view to providing theoretical reference for future groundwater pollution remediation efforts.

The authors analyzed the environment protection measures and effectiveness of the environmental activities atCherepovetsiron and steel works which is situated vitally close to the specially protected natural area of international importance Darwin Nature Reserve. They show that the measures taken cover all essential issues to decrease the negative impact of the iron and steel works on the local ecosystems and human health according to the modern world practice. The measures include defining the basic pollutants and monitoring their release, modernizing manufacturing equipment to reduce contaminated wastewater discharges, air and soil pollution, safe disposal of industrial waste and diversified monitoring of the local environment. The above mentioned activities resulted in significant reduction of industrial waste, reduced water consumption and decrease in wastewater and soil pollution. After analyzing data of the independent monitoring of the environment the authors noted high efficiency of environment protection activity carried out in different years atCherepovetsiron and steel works. The results of the studies and the authors’ field research inDarwinnature resort showed improvements in the environmental conditions in the local area including improvement of the general state of the nature resort’s ecosystems. The state of the environment has basically improved, for example, in the past 5 years the air inCherepovetshas become cleaner, the pollutant content in soil and vegetation inDarwinnature resort area has also reduced.

With the strengthening of human activities, more and more sulfur had entered soil system. The sulfur pollution of soil had threaten environment and human health. This paper reviews the status, sources and danger of sulfur pollution soils, and the physical-chemical remediation and bioremediation technology are also discussed. In addition, the future study on remediation technology for sulfur pollution soils was prospected.
