| 摘 要： | 作物群体结构具有重要的生态学意义。在农田生态系统中 ,不同的群体结构可形成不同的辐射场、风场以及农田的小气候环境特征。文章对主要的作物群结构参数 (如株高、茎粗、叶面积指数、叶倾角、叶方位角等 )所产生的生态环境效应进行了探讨 ,并总结了理想作物群体结构构建的标准与途径。

| Abstract: | The structure of crop community plays an important ecological roles in farmland ecosystems.Different crop community may bring about different radiant field,wind field and micro climate.The ecological effects of main factors of crop community structure(including height of canopy,thickness of stem,leaf area index,leaf incidence and azimuth,ets.) are discussed,and the standards of construction of crop community structure are put forward as well. |

| Keywords: | crop community structure ecological effect optimization |
