| 研究了浙江省临安市不同经营措施类型山核桃人工林的物种多样性，结果表明：（1）绵枣儿、天葵、麦冬、地丁、鹅观草、猪殃殃等物种在各经营类型林地中重要值相对较高。（2）丰富度指数在16～33之间，均匀度指数在0.7205～0.8537之间，Simpson指数在0.8327～0.9304之间，Shannon-Wiener指数在3.0750～4.2288之间。（3）类型C的Shannon -Wiener指数和丰富度指数低于类型A和类型B，Simpson指数大小依次为：类型A>类型B>类型C，均匀度指数类型A与类型C基本相等，而类型B最少。（4）对于类型C我们要改变林地的经营措施加速林下植被的恢复，合理引入绵枣儿、天葵、麦冬、地丁、鹅观草、猪殃殃等适应性较强的物种。 |

| Abstract: |
| The characteristics of species diversity of different types management measures Carya cathayensis Sarg.; artificial forestry were studied. The results were as follows: Firstly, the species such as Scilla scilloides (Lindl.) Druce, Semiaquilegia adoxoides (DC.) Makino, Ophiopogon japonicus (Linn. f.) Ker-Gawl, Viola philippica Cav, Roegneria kamoji Ohwi, Galium aparine Linn. var. tenerum Gren.et Godr had a comparable higher important value index in every community type. Secondly, the richness index of shrub layer species of different community types ranged from 16to33, and the evenness index from 0.7205 to0.8537; the Simpson index from 0.8327 to0.9304, the Shannon-Wiener index from 3.0750 to 4.2288. Thirdly, The species richness index and Shannon-Wiener index of type C were lower than those of the other two types, the Simpson index order was type A> type B> type C and the evenness index order was type A and type C is basically the same, and type B was at least. Fourthly, for type C, suitable measures should be changed to accelerate the restoration of understory vegetation, including introducing endurable species, such as Scilla scilloides (Lindl.) Druce, Semiaquilegia adoxoides (DC.) Makino., Ophiopogon japonicus (Linn. f.) Ker-Gawl., Viola philippica Cav, Roegneria kamoji Ohwi, Galium aparine Linn. var. tenerum Gren.et Godr. to improve the recovery course of undergrowth vegetation. |
