Accelerating urbanization and industrialization have had substantial impacts on economic and social activities, changed the surface environment of the earth, and affected global climate change and biodiversity. If reasonable and effective management measures are not implemented in time, unchecked urbanization and industrialization will damage the structure and function of the ecosystem, endanger human and biological habitats, and ultimately lead to difficulties in achieving sustainable development. This study investigates the habitat quality effect of land use transition and analyzes the cause and mechanism of such changes from an economic–social–ecological complex system perspective in the Henan Water Source (HWS) area of the Middle Route of the South-to-North Water Transfer Project (MRP). The study comprehensively examines the characteristics of land use transition from 2000 to 2020. The results indicate that the habitat quality of the HWS area of the MRP decreased slowly over the past 20 years, with a more obvious decrease in the past 10 years. Specifically, the proportion of high quality habitat areas is relatively large and stable, and the medium and low quality habitat areas increase significantly. Analyzing the change degree of the proportion of different levels of habitat quality area in each county, revealed that Dengzhou City had the most dramatic change, followed by the Xichuan and Neixiang counties; other counties did not undergo obvious change. The results of habitat quality factor detection by GeoDetector showed that land use transition plays a decisive role in the change of habitat quality. The types of land use with high habitat suitability compared to those with low habitat suitability will inevitably lead to a decrease in habitat quality. Additionally, elevation, slope, landform type, and annual precipitation are important factors affecting the habitat quality in the HWS area of the MRP, indicating that ecological factors determine the background conditions of habitat quality. The gross domestic product (GDP) per capita, the proportion of agricultural output value, grain yield per unit area in economic factors, population density, and urbanization rate in social factors affect the spatial differentiation of habitat quality to a certain extent. Soil type, annual mean temperature, vegetation type, and NDVI index have weak effects on habitat quality, while road network density and slope aspect have no significant effect on habitat quality. The results of this study provide a basis for the improvement of habitat quality, ecosystem protection and restoration, land resource management, and related policies in the HWS area of the MRP. They also provide references for the research and practice of the habitat quality effects of land use transition in other regions.

To comply with the national strategic layout adjustment in recent years, and to promote ecological civilization construction in China western region, it is necessary to study the opportunities and challenges in the Western Route Water Transfer demonstration brought by in ecological and environmental changes in both water-source regions and water receiving regions. By referring to the operation management experience of the Eastern and Middle routes of the South-to-North Water Transfer Project, this paper analyzed the ecological and environmental changes of the Western Route Project’s water transfer rivers, and the relationship between water and sediment of the Yellow River in water-receiving regions, found out the integrating point between the Western Route Project and the new development ideas, and finally concluded that the ecology must be given to priority in the demonstration of the Western Route Project. The early stage work of the Western Route Project needed to follow the general principles as for any major water conservancy project, which includes to demonstrate the project necessity given fully employing the water-saving potential, and to give highest priority to ecological security. Several relationships need be coordinated between: water source regions and water-receiving regions in water-saving, water ecological restoration and water resources development, water pollution control and water resources management, government leading and society participation, etc. These instruments above will guarantee both the water-source and water-receiving regions could benefit from the Western Route Project, help to solve the contradiction between ecological protection and water resources allocation, and facilitate achieving the target of sustainable development.

Water Amount

The South-to-North Water Transfer Project plays an important role in guaranteeing the sustainable development of economy and society in North China. The first phase of the middle route of the South-to- North Water Transfer Project (m-SNWTP) has been running safely in the past three years, and the dispatched water amount is increasing. This paper mainly describes the water operation of the m-SNWTP and the groundwater protection in the water-receiving areas. Up to the end of June 2018, more than 1.4×1010m3water had been supplied to the m-SNWTP benefited regions, including 8.65×108m3environmental water. In addition, the m-SNWTP provides water source guarantee for the environment restoration. Over 1.326 ×109m3overexploited groundwater has been reduced in the urban areas of the water-receiving areas, and the continuous decline of groundwater level has been effectively curbed.

The Impact

Land use change has an impact on the ecosystem service value because it changes the structure and function of ecosystems. This paper analyzed the changes in land use during the period from 2000 to 2015 in Shangzhou district, and used the equivalent value of ecological services per unit area of land ecosystem combining the natural and economic conditions of Shangzhou district. Based on this method, the ecological service value of Shangzhou district was estimated, and the impact of land use change on the ecological service value was analyzed. The results showed that: (1) the main types of land use in Shangzhou district were grassland, woodland and farmland, among which the contribution rate of woodland to the value of local ecosystem services was the highest; (2) the overall trend in the ecosystem service value in Shangzhou district increased between 2000 and 2015, from 10.74 × 108 yuan in 2000 to 20.32 × 108 yuan in 2015, which is the result of the combined effects of regional economic development and changes in the natural environment and land use patterns; and (3) the main reason for the value increase of ecosystem services in Shangzhou district between 2000 and 2015 was that the grain-for-green policy transformed a considerable amount of farmland into woodland, while the main reasons for a decline in value was the expansion of built-up land that occupied other types of land.

Scientific Decision

An inter-basin water transfer project is one of the effective ways to resolve the problem of an uneven distribution of water resources. Temporal and spatial variations in rainfall in different basins greatly affect water supply and demand in inter-basin water transfer projects, leading to risks to the operation of the water transfer projects. This paper applies a Bayesian network model to analyze this risk and studies the rich–poor rainfall encounter risk between a water source area and water receiving areas in the middle route of the South-to-North Water Transfer Project in China. Real time scenario simulations with the input of new observations were also studied. The results show that the rich–poor rainfall encounter risk is high for the Tangbai River receiving area in the fourth quarter, for the Huai River and South of Hai River receiving area in the second quarter, and for the North of the Hai River receiving area in the fourth and first quarters. The scenario simulations reflect risk change in the operation of water transfer projects, providing scientific decision support for the management of the water resource distribution in the inter-basin water transfer projects.

The Cost

Abstract Reasonable eco-compensation standards are conducive to increasing the enthusiasm of residents in the water source area of the water diversion project for ecological environmental protection and maintenance and for improving the water quality security of the water receiving area. In this paper, a comparative analysis of calculation mechanisms, formulas, and results of 7 types of eco-compensation standard methods for the Middle Route Project of the South-to-North Water Diversion Project in China is conducted. The research shows that the calculated results for the 7 types of methods differ greatly and considers that the cost and ecological service value methods are appropriate. Using this as the basic method to consider introducing market value of water resources, internal income of water source area, and government financial support for method improvement, the results show that the improved methods can reduce the gap between the per capita income of the water source area and the reference area, increase the satisfaction of both the water receiving area and the water source area, and provide support for overall socioeconomic development.
