Rural Landscape Fragmentation in Urban Fringe Areas
Since the Agricultural Development Act Amendment has been enacted in 2000, the era of free trade in farmland began and brought great impact on rural landscape. In order to explore rural landscape fragmentation, three typical countryside villages such as Weiqian, Dazhou, and Dayi, of Sanxing Township were taken as the experimental areas. The Markov model was applied to predict future landscape changes, and landscape indices were used to analyze rural landscape pattern. There are several findings in this paper: (1) Farmland is the main landscape matrix of our research region during 1987~2009, but the ratio is declining. If we keep developing it based on the rate of 2000~2009, constructs would convert into farmland and become main land type in 2054. (2) Due to road network construction, landscape was in the stage of dissection of landscape fragmentation in 1987~2000. But in 2000~2009, because of constructs clustering, it was in the stage of shrinkage toward attrition. (3) Judging from higher increasing speed of constructs and severer phenomenon of landscape fragmentation, we suggest policy is an important factor to rural landscape fragmentation. (4) Rural landscape fragmentation became worse during 1987~2009 and transformed cultivation landscape into peri-urban landscape ,then ecosystem services including provisioning services, culture services, regulating services and supporting services have been destroyed. The Government should grapple with this phenomenon seriously, and take actions to solve the problems.
