Spatio-temporal dynamic patterns of farmland and rural settlements in Su–Xi–Chang region: Implications for building a new countryside in coastal China

This paper analyzes the spatio-temporal dynamic patterns of farmland and rural settlements from 1990 to 2006 in Su–Xi–Chang region of coastal China experienced dramatic economic and spatial restructuring, using high-resolution Landsat TM (Thematic Mapper) data in 1990, 1995, 2000 and 2006, and socio-economic data from both research institutes and government departments. To examine the spatial patterns of farmland and rural settlements and their change over time, a set of pattern metrics that capture different dimensions of land fragmentation was identified. The outcomes indicated that, to a large extent, land-use change from 1990 to 2006 in Su–Xi–Chang region was characterized by a serious replacement of farmland with urban and rural settlements, construction land, and artificial ponds. Population growth, rapid industrialization and urbanization are the major driving forces of farmland change, and China's economic reforms played an important role in the transformation of rural settlements. China's “building a new countryside” is an epoch-making countryside planning policy. The focuses of building a new countryside in coastal China need to be concentrated on protecting the farmland, developing modern agriculture, and building “clean and tidy villages.” Rural construction land consolidation and cultivated land consolidation are two important ways to achieve the building objectives. The authors argue that it is fundamental to lay out a scientific urban–rural integrated development planning for building a new countryside, which needs to pay more attention to making the rural have certain functions serving for the urban. In addition, the cultural elements of idyll and the rural landscape need to be reserved and respected in the process of building a new countryside in coastal China, instead of building a new countryside, which looks more like a city.
