中文摘要	试验研究表明,在春小麦全生育期进行补充灌溉和升高CO_2浓度能够有效提高田间生态系统边缘效应.与没有CO_2浓度升高比较,当CO_2浓度升高40～160mumol/mol时,舂小麦田间生态系统边缘效应的面积增加1.8～3.6m~2.在春小麦全生育期补充灌溉60mm与补充灌溉30mm比较,田间生态系统边缘效应有显著变化.特别是将CO_2浓度升高与补充灌溉进行组合,较没有CO_2浓度升高与补充灌溉比较,春小麦田间生态系统边缘效应面积提高了300%～500%.同时研究还表明,在春小麦全生育期CO_2浓度升高与补充灌溉可以显著提高春小麦田间生态系统边缘效应系数.CO_2浓度升高与补充灌溉进行组合较没有CO_2浓度升高与补充灌溉比较,边缘效应系数提高4.0～6.7.因此,CO_2浓度升高与补充灌溉组合对提高春小麦边缘效应有显著作用.
英文摘要	In this study, our aim is to clarify the dynamic changes of border effect of spring wheat field system under elevated CO_2 concentration and supplemental irrigation in a semiarid region of China. The experimental results showed that elevated CO_2 concentration and supplemental irrigation could improve the effect of crop border. In elevated CO_2 concentration from 40 to 160 mumol/mol, the border effect area was improved by 1.8～3.6m~2 in comparison with that without elevated CO_2 concentration. The border effect area, in supplemental irrigation 60mm, was significantly changes than that in supplemental irrigation 30 mm and without supplemental irrigation. Specially, under the combination of elevated CO_2 concentration and supplemental irrigation, the border effect area was improved by 300%～500% in comparison with that without elevated CO_2 concentration and supplemental irrigation. At the same time, the experimental results showed that the elevated CO_2 concentration and supplemental irrigation could decrease the core area/border effect area (Q). In the combination of elevated CO_2 concentration and supplemental irrigation, Q was decreased by 4.0～6.7 in comparison without elevated CO_2 concentration and supplemental irrigation. Thus, the combination of elevated CO_2 concentration and supplemental irrigation played an important role in the improvement of the effect of spring wheat border.
