银川郊区小麦田杂草发生规律、群落结构及多样性研究

摘 要

本文采于2012年4-7月对银川郊区小麦田杂草发生种类与分布、发生规律进行了较为系统的调查，并运用相对多度（RA）和Simpson 指数(J)、Shannon—Wienner 指数(H

)、Pielou均匀度指数（E）、Mcintosh指数(DMC)对小麦田杂草群落结构和多样性进行了分析。结果表明，银川郊区小麦田杂草种类有13科29属34种，其中藜、扁蓄、打碗花等十余种杂草分布广泛；小麦田杂草发生高峰在五月中旬;杂草群落结构为藜+禾本科+扁蓄+打碗花。不同调查田块小麦田杂草物种多样性指数、丰富度指数、均匀度指数随着调查地点呈现由东向西、由北向南呈现下降趋势，同一地点不同时间小麦田杂草多样性则呈现随前期逐渐增加，而后期下降的规律性变化。

摘要Abstract
本文采于2012年4-7月对银川郊区小麦田杂草发生种类与分布、发生规律进行了较为系统的调查，并运用相对多度（RA）和Simpson 指数(J)、Shannon-Wienner 指数(H)、Pielou均匀度指数（E）、Mcintosh指数(DMC)对小麦田杂草群落结构和多样性进行了分析。
Based on the quite systematic researches / investigations carried during April-July 1012 on the weed species and its distribution as well as the occurrence regularity in the wheat field of Yinchuan outskirts, this paper analyzed the weed community structure and diversity of the wheat field using the relative abundance (RA), Simpson index (J), Shannon-Wienner index (H), Pielou evenness index (E) and Mcintosh index (DMC).
结果表明，银川郊区小麦田杂草种类有13科29属34种，其中藜、扁蓄、打碗花等十余种杂草分布广泛；小麦田杂草发生高峰在五月中旬；杂草群落结构为藜+禾本科+扁蓄+打碗花。
The results showed that there are 13 families 29 genera and 34 species of weeds in Yinchuan outskirts wheat field, in which more than ten kinds of weeds such as Chenopodium, Polygonum aviculare and Calystegia hederacea etc. are widely distributed; the peak of wheat field weeds happen in the middle of May; the weed community structure is Chenopodium + graminaccae (gramineae) + Polygonum aviculare + Calystegia hederacea.
不同调查田块小麦田杂草物种多样性指数、丰富度指数、均匀度指数随着调查地点呈现由东向西、由北向南呈现下降趋势，同一地点不同时间小麦田杂草多样性则呈现随前期逐渐增加，而后期下降的规律性变化。
The species diversity index, richness index, evenness index of weed in different block of wheat field investigated presented a trend that they decrease from east to west and from north to south, and presented a regular change that, at the same location but different time, the weed diversity increases at early stage and decrease at late stage.

Answer 2

This gift on July 4, 2012 in yinchuan suburban cornfield weed species and
distribution law of a systematic investigation, and using the relative abundance
(RA) and Simpson index (J) Shannon Wienner index (H），Pielou evenness index (E), Mcintosh index (DMC) to the cornfield weed community structure and diversity were analyzed. Results show that yinchuan suburban cornfield weed species there are 13 families, 29 genera and 34 species, quinoa, Armstrong, a bowl of flowers, such as more than 10 kinds of weed widely distributed; Peak in mid-may cornfield weed occurrence; Weed community structure of quinoa + grass + flat + storage bowl of flowers. Different investigation plots in cornfield weed species diversity index, richness index and evenness index as the investigation site rendering from east to west, from north to south presents the downward trend, the same location at different times the cornfield weed diversity are gradually increased along with the early, late and decline regularity of the change.
