LUCC视角下神农架地区植被景观特征及其变化研究

分析研究不同LUCC景观在空间和时间尺度上的特征及动态变化具有重要科学价值和实际意义.利用景观生态学方法与地统计学方法分析了1990年、2000年、2005年、2010年、2015年神农架地区LUCC植被景观的生态学指数，探讨了神农架地区LUCC植被景观的统计学特征、多样性特征、异构性特征、复杂性特征.在LUCC理论方法指导下，对神农架地区植被景观的基本特征进行了分析研究，并对神农架地区植被景观特征的变化过程和规律进行了探讨.结果表明，神农架地区LUCC植被景观总体上稳定性非常强；林地类植被景观、草地类植被景观处于稳定向好状态；耕地类植被景观处于缩减紧凑状态，是退耕还林的结果；湿地类植被景观变化表明神农架地区湿地保护还有待加强.

Research on the characteristics of vegetation landscape and its change in Shennongjia Area from the perspective of LUCC

To study and analyze different LUCC landscape's characteristics and dynamic changes in the spatial and temporal scales is of great scientific value and practical significance. This paper adopts the methods of landscape ecology and geostatistics to analyze the ecological index of LUCC vegetation landscape in Shennongjia Area in 1990， 2000， 2005， and 2010. The statistical characteristics， diversity characteristics， heterogeneity characteristics and complexity features of LUCC vegetation landscape in Shennongjia Area were discussed. Under the guidance of LUCC theory， the basic characteristics of vegetation landscape in Shennongjia Area were analyzed and studied， and the changing process and laws of vegetation landscape characteristics in Shennongjia Area were discussed. The result shows that the overall stability of the LUCC vegetation landscape in the Shennongjia Area is very strong. The forestland vegetation landscapes and grassland vegetation landscapes are in a stable and good state； arableland vegetation landscapes are in a state of shrinking compactness， which is the result of returning farmland to forests. Changes in wetland vegetation landscapes indicate that the wetland protection in Shennongjia Area needs to be strengthened.
