  • “山水林田湖草”重大生态保护与修复工程是中国对复杂生态环境治理的重要探索。鉴于目前大多数重大生态工程未系统地考虑气候变化对重大生态工程的影响问题,针对气候变化对高寒草地、北方林区以及风沙源区生态的影响,以实施了多年的三江源生态保护工程、三北防护林工程和京津风沙源治理工程为重点,分析了重大生态工程对全球气候变化的响应,解构了重大生态工程与气候的反馈关系和影响程度,指出了中国“山水林田湖草”重大生态工程实施过程中可能存在的问题,并给出了应对建议。结果表明:(1)气候变化对重大生态工程影响研究不足,尤其是涉及区域生态系统结构、功能、生物多样...

    以荒漠优势植物红砂2年生苗木为试材,采用盆栽试验和开顶式CO2控制气室模拟CO2浓度变化(350μmol/mol和700μmol/mol)研究了红砂生物量分配及碳氮特征对降水变化减少30%、减少15%、自然降水、增加15%和增加30%(-30%、-15%、0、15%、30%)的响应。结果表明:(1)CO2浓度上升显著性的促进红砂地上茎叶和地下的根生物量,降雨量增加或减少也显著性的促进或抑制了这一作用;CO2倍增时,红砂的地上生物量在降水增加30%时平均增加了61.28%(P < 0.05),而根生物量在降水增加或减少30%时均分别增加...

    碳捕集与封存(Carbon Capture and Storage,CCS)是应对全球气候变化、实现煤炭清洁利用的有效手段之一,但是地质封存的CO2存在泄漏的风险,可能对农田生态系统产生重大威胁,影响我国粮食安全。根系生长是地上部和地下部相互作用、相互促进的统一过程,其形态特征对作物生产力有显著影响,但CCS泄漏对植物根系的影响评估尚不多见。本文以玉米为研究对象,采用盆栽底部通入CO2的方法模拟不同CO2泄漏情景,研究CK(0 g m-2 d-1)和G1000(1000 g m-2 d-1)和G2000(2000 g m-2 d-1)...
