| 摘 要： | 以湖南农业大学为研究区,对2005年和2010年的遥感影像进行土地利用景观分类,选取并计算具有代表性的景观指数,结合GIS的空间分析技术,从景观的总体和单元特征、空间构型和景观异质性等方面对景观变化情况进行分析。结果表明,经过五年的建设,研究区大量其他景观转变为绿地景观、道路景观、生活设施景观、娱乐场地景观及教学设施景观。尽管土地利用程度加大,但景观格局日趋合理,功能分区进一步明确,且生态环境得到较好的保护。

| Abstract: | Taking Hunan Agricultural University as a study area,through interpreting and classifying 2005 and 2010 remote sensing images according to land use landscape classification principles,using the landscape index and GIS spatial analysis technology,spatial pattern and evolution of two periods were analyzed from 4 aspects including the overall landscape and unit characteristics,heterogeneity and spatial configuration of landscape evolution analysis. The results showed that lots of other landscape converted to the green landscape,road landscape,living facilities landscape,entertainment venues landscape and teaching facilities landscape after 5 years of construction. Although the extent of land use degree increased,but the landscape pattern has been reasonable gradually. The functional partition is made clear further and the ecological environment is to be better protected. |
