摘要:统计分析表明 ,研究区域内森林类型多样性整体分布格局是 :大多数村包含 2个不同的森林类型 ,由北向南森林类型逐渐增多 ,并呈镶嵌分布。采用最大覆盖模型研究森林类型多样性与保护地的优化选择 ,模型用贪心法求解 ,最终得到森林类型多样性的最大覆盖格局包括瓦房庄村、北堂村、孔沟村和竹园村 ,共 5个村。以这 5个村作为研究区的森林类型多样性保护地比较合适。指出 ,在研究区内 ,森林类型多样性可能并非完全是自然形成的 ,不能排除人为因素的影响。
Statistics analysis showed the general pattern of forest type diversity in studied area: most villages had forest type of two predominant tree species;the number of forest type in mosaic pattern increased from the northern to the southern. A maximal covering model on forest type diversity and reserve selection had been built .The model was solved by greedy algorithm,and five villages had been selected for the maximal covering pattern of forest type diversity and they were suitable for reserve sites. The forest type diversity was probably not only formed by nature, human influence could not be completely excluded in the studied area.
