| 摘 要： | 采用系统生态学方法,对浙江省淳安县千岛湖镇土地利用变化导致的生态效应进行了初步定量分析与研究。结果表明:在景观尺度水平上,千岛湖镇在合理的生态功能规划下,各种景观类型分布趋于聚集,形成一定的规模;单类景观占据主导的趋势在减弱,将导致生态系统的稳固,同时,随着林地的不断较少,城镇化水平的不断提高,生态环境将会受到一定的影响。具体表现在:生境质量下降;景观内部均质化发展,降低了景观抗干扰能力;边缘效应降低;生态系统组分单一化。

| Abstract: | By the methods of systematic ecology,the ecological effects of ten years land use changes were quantitatively analyzed in Qian-dao Lake town with rapid rural urbanization of Chun-an County,Zhejiang Province,aimed to provide a scientific basis for healthy development of towns and small cities in China.The results showed that each kind of landscape type distribution of Qiandao Lake town tended to gathering and formed the certain scale in the scale of landscape and the tendency of the single kind of landscape ... |
