| 摘 要： | 运用遥感和地理信息系统技术,选择斑块数、香农多样性指数、形状指数、比邻指数等多个景观指数,基于300 m粒度值,分别从类型水平和景观水平两方面分析广东省韶关市1993年、2004年土地景观格局动态变化情况。结果表明,韶关市林地景观受到侵蚀分割,水域景观较为稳定,耕地景观的移入率和移出率较高,建设用地处于分散化的非平衡过程中,整体景观异质性和破碎化程度增强。

| Abstract: | By adopting RS and GIS technology,and selecting several landscape indices including NP,SHDI,LSI,IJI and so on,the variation of landscape pattern in Shaoguan of Guangdong Province in 1993 and 1994 was analyzed from the perspectives of landscape type and level based on the grain size of 300 m.The results indicated that,the forest landscape in the study area was eroded and divided,while the water landscape remained relatively stable,farmland enjoyed a high input and output rate,construction land was in the pro... |
