摘    要:东北平原农田防护林已经形成了比较完整的林网体系。本研究分析了农田防护林网全方位的防风作用、防霜作用以及林网内的综合气候效益场。在林网内,全方位防风效能大于10%的区域为防护效益区。作物产量和质量分析表明,林网的防护范围为25倍树高。根据高生长分析确定了构成农田防护林主要杨树品种的成林高度。根据综合分析确定适宜农田防护林网的规格为400m×400m。图7表3参11。

关 键 词:农田防护林  防护效益  林网  规格  防风效能

Abstract:The farmland shelterbelts in Northeastern Plain of China have formed relatively complete net system. The functions of shelterbelt net in omnibearing wind check and prevention of frostbite as well as the field of integrated climate effect within shelterbelt net were analyzed, through located observation of meteorological factors. Within the shelterbelt net, the area with more than 10% efficiency of omnibearing wind check was determined as benefited area. The analysis of yield and quality of crops indicated that the sheltering range of shelterbelt net was 25 times tree height. The mature heights of the various varieties of poplar composed the shelterbelts were determined according to their height growth. Based on the comprehensive analysis above, the suitable size of farmland shelterbelt net in Northeastern Plain of China was decided to be 400 m×400 m.
