基于遥感的泉州湾河口湿地互花米草分布扩散分析

Analysis of Spartina alterniflora Distribute and Spread in Quanzhou Estuary Wetland Based on Remote Sensing Technology

运用遥感技术,采用监督分类法提取1988—2005年泉州湾河口互花米草;运用景观生态学方法,对互花米草进行景观格局分析,探讨互花米草的分布扩散规律。研究表明,泉州湾河口湿地互花米草扩散规律为:先在某些地点定居,通过快速扩散和生长,由点变成面后集中连成片,然后再向更远的距离扩散,如此循环往复,直到达到一定的环境容量。

Using the supervise classification method to extract Spartina of the Quanzhou bay from 1988 to 2005 with the remote sensing technology.In order to recognize the distribution rule of Spartina,landscape ecology method is utilized to analyze Spartina’s landscape pattern.Through the analysis,we discovered the spreading rule of Spartina,i.e.Spartina first settled down in certain places,then spread and growth fast,after that,the spot Spartina grew to concentrate continually piece Spartina,then to the farther distance proliferation,and they repeated in cycles,until it reached certain environmental capacity again.
