摘要
本文对胡家林场天然林早春植物多样性进行研究,结果显示:科、属和物种的丰富度指数和Shannon-Wiener多样性指数逐年降低;优势度升高。物种丰富度指数和Shannon-Wiener多样性指数明显差异大,而生态优势度D变化不明显。
Study of forest natural forest early spring plant diversity at Hujia forest farm. Shannon - Wiener diversity index decreased year by year; dominance increased. Species richness index and Shannon -Wiener diversity index difference, while ecological dominance of D did not change significantly.
