采用林窗边缘效应测定的方法，对茅台水源功能区次生林分林窗，开展边缘效应及林窗大小关系研究。共调查23个林窗，面积分布在75～300m2。通过对不同大小林窗中树种多样性、边缘效应强度研究，揭示了随着面积的增大，林窗树种的多样性和均匀度增加，优势度降低，其边缘效应在小范围内波动的规律。根据边缘效应起伏的波谷值，将林窗划分成4个大小等级：〈100m2、100～150m2、150～240m2、〉240m2。各等级的树种多样性、边缘效应强度不同，其中150～240m2处，边缘效应强度最强，其次为〉240m2。

Using the edge effect determination, the relationship between edge effect and size of 23 secondary for- est gap was studied in Maotai water functional areas and the size ranges from 75 m2 to 300 m2. Through species di- versity and edge effect on different gap sizes, the study revealed that with the increase of size, the diversity and evenness go up, but dominance goes down, and their edge effect fluctuates in a small scope. Based on troughs of rolling edge effect, gap size is divided into four levels：〈 100 m2, 100-150 m2, 150-240 m2 and 〉240 m2. Each level has different diversity and edge effect. When in 150-240 m2, the edge effect reaches the strongest, followed by 〉 240 m2.
