Onset: the disease may recurrently attack for many years.

The area of coniferous forests and shrubs both increased. Virgin forest were distorted seriously in there area of coniferous forests and latifoliate forests were decreased before 1990. Shrub areas decrease largely between 1990 and 2000.

1990年以前，原始林地的破坏严重，针、阔叶林的面积减少，1990-2000年间灌丛的面积大幅度减少，2000年以后，针叶林、混交林、阔叶林的面积均略有减少。

The whole conditions of sporopollen imply warm cool and moist climate of temperate zone at that time, suggesting wide distribution of deciduous and latifoliate forests.

孢粉总的面貌反映了温凉、湿润的温带气候，指示了落叶、阔叶森林广泛分布。

The Greenland amount of latifoliate forest is in the majority, and the next is the forest type mixed by broadleaf and conifer.

森林公园中阔叶林的绿量最高，其次是针阔混交林，木荷林对福州国家森林公园绿量贡献最大。

Niche overlaps between Festuca sinensis and other species were smaller than that between two latifoliate herbs species in most case.

以中华羊茅为其中一个组分种的植物种对间的生态位重叠值，在大多数情况下小于两种阔叶杂草种对间的生态位重叠值。
