Abstract:In recent years, food security, especially supply, has been an important issue in China's agricultural production. The stability of grain prices is related to the stability and development of the grain market. Based on agricultural production data from 1970 to 2015, this paper explores the influence of agricultural product price fluctuation on grain production by using the cobweb theory and vector error correction (VEC) model. The results show that changes in grain production in China are affected by fluctuations in agricultural product prices, that the production change lags behind the price change, and that there is a long-term equilibrium relationship between grain yield and agricultural product price. A Granger causality test shows that the change in agricultural product price is the Granger cause of grain yield change.

“…To conduct spatial analyses and statistical analyses of the dynamic change in land use patterns it is necessary to adopt and improve upon research methods in the field of spatial geography [21]. Li and Liu use several effective software packages to carry out spatial analysis, including ArcGIS 10.3 and ENVI 5.3 [7].…”

Achieving sustainable land use is one of the most important ways to achieve regional socio-economic sustainable development. We have collected 12 papers in this special issue "Sustainable Land Use in China" to show the varied application of sustainable land use studies and to provide meaningful decision-making information and policy implications for land use planners. We summarize the contributions to this special issue on sustainable land use and place them in perspective. Several studies focus on sustainable urban land use, some focus on sustainable rural land use, and others on environmental issues on land use. These studies have analyzed a broad array of topics related to land use, including the dynamic changes and driving forces of land use spatial patterns, sustainable land use, land use policy and optimization, and the environmental problems related to certain types of land use.

“…Sprawl can be limited by establishing rigorous restrictions and heavy financial penalty policies of development activities outside the urban planning boundary. Thirdly, governments should adopt different planning control methods and incentive policy according to different regional features [70,71].…”

The Effectiveness of Planning Control on Urban Growth: Evidence from Hangzhou, China

Fan

et al. 2017

Urban sprawl presents a serious challenge for sustainable urban land use. Urban planning attempts to guarantee sustainable urban development and proper use of land resources. However, a large gap usually exists between planning and actual development. This paper aims to analyze the evolutionary characteristics of urban form and the spatiotemporal dynamics of urban planning from 1964 to 2013, using the case of Hangzhou, China. We proposed a framework that included remote sensing, landscape metrics, and control effectiveness indexes. The results indicated that urban planning failed to perform effectively in Hangzhou, reflected by the uncontrolled urban sprawl during all the planning periods. The low effectiveness of planning was resulted from multiple factors, including historical economic events that made expansion unexpected, functional orientation of planning which drove fragmented suburbanization, the ineffective methods for forecasting population and land use, and the influences by the market forces. The findings deepen the understanding of the impacts of urban planning, and provide references for making rational urban management decisions and sustainable urban land management.
