| 摘要: |
| 本文对黑龙港流域的农田林网辐射平衡状况初步研究表明:晴天总辐射林网外比林网内大5%;阴天林网内外几乎没有差异。林网内外散射辐射差异不大;但是网内散射辐射占总辐射的比例比网外大2%。晴天林网内有效辐射比林网外小6%。晴天辐射平衡林网内比林网外大4%。表明林网在一定程度上改变林网内农田活动层辐射平衡各分量的再分配;说明林网对网内作物生长小气候环境起了调节作用。 |

| Abstract: |
| This paper has dealt with Various components of radiation balan- ce at a shelter belt network in the field along Heilonggang River. The result showed:In a sunny day total rariation inside of a net- work was 5% as large as outside of a network,in a overcast day th- ere was no difference inside and outside of a network.Inside and outside of a network difference of scattered rddiation was not apparent but inside of a network of scattered radiation propertion of total ra- diation was larger than 2% outside of a... |
