摘要
运用景观生态学的研究方法,借助于ArcGIS9.3和Fragstats3.3,以2011年田东县土地利用变更调查成果为基础,选择合理的景观指数,对田东县不同地貌形态的平马镇、义圩镇和作登乡耕地景观空间格局进行分析。研究表明:受地形地貌和人类活动的影响,同一地貌形态区旱地的破碎化程度高于水田;不同地貌形态区耕地破碎化程度右江河谷的平马镇相对较低,北部土石区义圩镇和南部石山区作登乡较高。
The analysis of the farmland landscape pattern in the different landform area of Pingma, Zuodeng and Yixu in Tfandong County, which was on the basis of the land use survey results of Tiandong County in 2011, was clone with the help of Arcgis9.3, Fragstats 3.3 and reasonable Jandscape index by using the method of landscape ecology.The results show that ： In the same landform area , the fragmentation degree of dry land being higher than paddy field, which was effected by human activities. In the different landform area , the farmland fragmentation degree of Pingma in the Yoqjiang PJver Valley was relatively low, while Zuodeng in Southern area with Rocky and Yixu in Northern area with Stone were relatively high.
