摘要: 科学评估覆盖作物种植体系的生态系统服务价值可以为东北地区保护性耕作模式构建提供重要参考。本研究基于实证分析,以生态系统服务价值为理论基础,选取禾本科作物黑麦草、豆科作物紫花苜蓿和毛苕子作为覆盖作物分别与玉米间作,以玉米单作模式为对照,从产品供给、气体调节、养分循环和水土保持四大生态系统服务方面进行生态系统服务价值的核算。结果表明: 覆盖作物-玉米间作模式的生态系统服务价值均高于玉米单作,其中养分循环价值最高,其次是产品供给价值,占比分别为67.3%和29.3%。覆盖作物-玉米间作模式的养分循环价值均高于玉米单作模式;紫花苜蓿-玉米、毛苕子-玉米的产品供给价值显著高于黑麦草-玉米,分别增加了18.7%和21.0%;种植覆盖作物具有增加气体调节价值的潜力,但对水土保持价值的影响较小。综合生态系统服务价值,选择豆科覆盖作物-玉米间作可以获得最大效益。

Abstract: Scientific evaluating ecosystem service value (ESV) of cover crop cultivation system can provide important guidance for the construction of conservation tillage pattern in Northeast China. Based on empirical analysis and the theory of ecosystem service value, we calculated the ESVs of intercropping maize with gramineous cover crop ryegrass and with leguminous cover crops, alfalfa and hairy vetch, with maize monoculture as the control. The ESVs included product supply, gas regulation, nutrient cycling, and soil and water conservation. Results showed that ESVs of cover crop-maize intercropping were higher than those of maize monoculture. Nutrient cycling value was the highest, followed by product supply value, accounting for 67.3% and 29.3% of total ESV, respectively. The nutrient cycling value of cover crop-maize intercropping was higher than that of maize monoculture. The product supply value of alfalfa-maize and hairy vetch-maize were 18.7% and 21.0% higher than that of ryegrass-maize, respectively. Cover crops had the potential to increase the value of gas regulation services, but had little impact on the value of soil and water conservation. Considering the ESVs, intercropping maize with leguminous cover crops would have the greatest benefits.
