Changes in Forest Spatial Patterns Driven by an Intensive Land Use Scenario in Jiangsu Province over the Past Three Decades
Changes in forest spatial distribution and disturbance patterns are of great significance for assessing the appropriateness of the adopted land use decisions, as well as the effectiveness of the existing forest management approaches. Based on the land use databases for 1980s. 1995 and 2000, a forest fragmentation model in concert with geospatial metrics was employed to characterize the status and trends of forest fragmentation and disturbance patterns over Jiangsu province in this analysis. The analytical processes used were based on the mathematical morphology, the percolation theory and the sliding window analysis techniques. Results suggested that the forest intactness status within the study time intervals took on a V curve, having the severest fragmentation for the forests in 1995. Additionally, the 1995 forests were heavily disturbed by anthropogenic activities, including the built-up sprawl and the restructuring of agricultural land uses. Findings in this analysis are closely related to Jiangsu development philosophy, tremendously demographic pressure and education arenas. The generated forest fragmentation and disturbance maps with spatially explicit information provide valuable insights and implications regarding the decisionmaking of future land use, the identification of conservation priority and the formulation of sustainable forest management strategies.
