| 摘 要： | 依据景观生态学原理,采用3S技术,对蕲春县土地利用景观格局进行定量的分析研究。结果表明:①该县2005年土地利用景观类型以林地为主,其次为耕地、水域和村镇建设用地;土地利用景观多样性较低,具有一定的优势景观;分维数较低,景观复杂程度不高;②该县中部丘陵地区和南部平畈围区土地利用景观多样性大于北部山区,但北部山区景观优势度较高。

| Abstract: | Based on the principles of landscape ecology,supported by 3S technology,the landscape pattern of land utilization in Qichun County is quantitatively analyzed in this paper.The results show that,firstly,the main types of land utilization are woodland,followed by farm land,water area,and township and village constructions in 2005 and the diversity of landscape is low,but the dominance index is high.The fractal dimension is low,and the complexity of landscape is not high.Secondly,the diversity of the central a... |
