With the continuous acceleration of urbanization process in our country, the conflict between demand of urban-rural construction land and limitation of land resources in area with rapid economic development is becoming sharper. Therefore, the research for planning and layout of urban-rural construction land is particular important. This paper takes Foshan City, Guangdong Province as an example. With GIS spatial analysis, divide the researched area into grids of some standard dimensions (20 m×20 m) through setting a group of construction permission elements; calculate the construction permission index of each grid (evaluation unit) and determine the proper land construction degree of different grids (evaluation unit) according to size of construction permission index; define areas with different construction degrees and strengths hierarchically; establish the guide rules of construction permission for each area to realize the reasonable spatial layout of construction land, so as to arrange reasonable space for newly increased urban-rural construction land in general planning of land use, achieving economical and intensive land use.

Rural Construction

Construction land expansion often occurs on cultivated land in developing countries during rapid urbanization and industrialization. Understanding its characteristics and driving mechanisms is of great significance for land-use policy and sustainable development. This paper depicted the spatio-temporal patterns of China’s urban–rural expansion and its occupation of cultivated land based on national land survey data from 1996 to 2006. It further explored the influencing mechanism of cultivated land occupation for urban–rural construction land. The results showed that the establishment and expansion of various economic development zones contribute to more than half of the occupation of cultivated land while the expansion of cities and towns is relatively slower, and their sources of construction land are more diverse. The empirical results showed that (1) economic growth and investment play key roles in shaping the spatio-temporal patterns of the occupation of cultivated land for urban–rural construction land, and (2) the mechanisms of cultivated land occupation in different stages of regional development are different. In particular, the establishment of national economic development zones is conducive to the intensive use of construction land and the protection of cultivated land in inland regions, whereas provincial economic development zones have led to a waste of land resources in coastal regions. Based on the results, this study suggested that the policies to the intensive use of land resources and cultivated land protection required regional disparities.

Rural Construction

With the rapid development of urbanization and industrialization, land exploitation in China has caused a decrease of cultivated land, posing a threat to national food security. To achieve the goals of both economic development and cultivated land protection, China launched an urban–rural land replacement measure supported by a new land use policy of “increasing vs. decreasing balance” of construction land between urban and rural areas in 2008. Setting China’s urban and rural land use policies in a historical context and urban–rural sustainable development, this paper discusses four practices in Jiangsu Province, Tianjin Municipality, Shandong Province, and Chongqing Municipality. These practices achieved success in impelling agricultural modernization development, improving rural infrastructure and living circumstances, releasing the potential of rural land resources, and increasing cultivated land and urban construction land in the past decade. However, in some practices, problems, and even some conflicts, exist in the protection of farmers’ rights and interests. These challenges are discussed in the context of implementation. In order to better implement urban–rural construction land replacement and achieve better results, the authors argue that farmers’ rights and interests must always be put first and their wishes should be respected more, a consolidated urban–rural land market and a better land market mechanism should be founded, the supply of public goods and services for villagers should be further improved, and supervision and evaluation mechanisms should be further strengthened.

Infiltration Recharge

The human activities and urbanization process have changed the underlying surface of urban areas, which would affect the recharge of groundwater through rainfall infiltration and may further influence the groundwater environment. Accordingly, it is imperative to investigate the variation of hydrological cycle under the condition of underlying surface change. Based on the high-precision remote sensing data of 2000, 2005, 2010 and 2015, and Soil and Water Assessment Tool (SWAT) model, this work firstly studied the land use change and the corresponding changes in runoff generation mechanism and rainfall infiltration coefficient in Su-Mi-Huai area, Beijing, China. Meanwhile, SWAT-MODFLOW semi-loose coupling model was applied to analyze the water balance in the study area in typical hydrological years. The results showed that the area of the construction land (urban and rural residential land) increased by 1.04 times from 2000 to 2015, which is mainly attributed to the conversion of cultivated land to construction land in the plain area. This change caused the runoff in the area to increase by 7 × 106 m3, the runoff coefficient increased by 17.9%, and the precipitation infiltration coefficient was less than the empirical value determined by lithology. Compared with 2000, the average annual precipitation infiltration coefficient in 2018 decreased by 6.5%. Under the influence of urbanization process, the maximum reduction rate of precipitation infiltration recharge is up to 38%. The study investigated the response of surface runoff and precipitation infiltration recharge to land use change, which can provide helps for water resources managers to coordinate the relationship between land use change and rational water resources planning.

Abstract In this study, we selected 11 townships with severe ground subsidence located in Weishan County as the study area. Based on the interpretation data of Landsat images, the Binary logistic regression model was used to explore the relationship between land use change and the related 7 driving factors at a scale of 60m * 60m. Using the CLUE-S model, combined with Markov model, the simulation of land use under three scenarios–namely, natural development scenario, ecological protection scenario and farmland protection scenario–were explored. Firstly, using land use map in 2005 as input data, we predicted the land use spatial distribution pattern in 2016. By comparing the actual land use map in 2016 with the simulated map of land use pattern in 2016, the prediction accuracy was evaluated based on the Kappa index. Then, after validation, the distribution of land use pattern in 2025 under the three scenarios was simulated. The results showed the following: (1) The driving factors had satisfactory explanatory power for land use changes. The Kappa index was 0.82, which indicated good simulation accuracy of the CLUE-S model. (2) Under the three scenarios, the area of other agricultural land and water body showed an increasing trend; while the area of farmland, urban and rural construction land, subsided land with water accumulation, and tidal wetland showed a decreasing trend, and the area of urban and rural construction land and tidal wetland decreased the fastest. (3) Under the ecological protection scenario, the farmland decreased faster than the other two scenarios, and most of the farmland was converted to ecological land such as garden land and water body. Under the farmland protection scenario, the area of tidal wetland decreased the fastest, followed by urban and rural construction land. We anticipate that our study results will provide useful information for decision-makers and planners to take appropriate land management measures in the mining area.
