摘 要:为了研究不同土地利用类型的净碳汇及其价值,为碳汇生态补偿提供依据,选择了河南省中北部6个土地利用类型中具有代表性的植物种类,用碳税法计算不同种类植物及不同土地利用类型净碳汇及其价值。结果表明,不同土地利用类型碳投入量,温室作物最大[2 037.88 kg/(hm^2·a)],其后依次为露地蔬菜[1 761.36 kg/(hm^2·a)]、粮经作物[1 390.92 kg/(hm^2·a)]、果园[1 226.57 kg/(hm^2·a)]、城镇绿地[350.76 kg/(hm^2·a)]、林地[198.93 kg/(hm^2·a)];不同土地利用类型固碳量,温室作物最大[16 283.70 kg/(hm^2·a)],其后依次为露地菜地[11 135.38 kg/(hm^2·a)]、粮经作物[10 694.70 kg/(hm^2·a)]、果园[5 234.00 kg/(hm^2·a)]、城镇绿地[4 783.94 kg/(hm^2·a)]、林地[4 364.11 kg/(hm^2·a)];不同土地利用类型净碳汇,温室作物最大[14 245.82 kg/(hm^2·a)],其后依次为露地蔬菜[9 374.02 kg/(hm^2·a)]、粮经作物[9 303.78 kg/(hm^2·a)]、城镇绿地[4 433.18 kg/(hm^2·a)]、林地[4 165.00 kg/(hm^2·a)]、果园[4 007.43 kg/(hm^2·a)];不同土地利用类型净碳汇价值,温室作物最大[13 120元/(hm^2·a)],其后依次为露地蔬菜[8 633元/(hm^2·a)]、粮经作物[8 569元/(hm^2·a)]、城镇绿地[4 141元/(hm^2·a)]、林地[3 836元/(hm^2·a)]、果园[3 691元/(hm^2·a)]。与林木相比,农作物净碳汇价值更高,建议把农作物净碳汇纳入生态补偿体系,减少农作物碳投入,提高农产品质量,充分发挥农作物净化空气的生态功能。In order to study the net carbon sink and their value of different land-use types,for providing basis for carbon sink ecological compensation,six land-use types including typical plant species were selected in north central region of Henan Province.The net carbon sink and their value of these land-use types and plant species were evaluated using carbon tax method.The results showed that,of all the carbon input of different land-use types,greenhouse crop was the highest[2 037.88 kg/(ha·a)],followed by field vegetable[1 761.36 kg/(ha·a)],food and cash crop[1 390.92 kg/(ha·a)],orchard[1 226.57 kg/(ha·a)],urban green land[350.76 kg/(ha·a)],forest[198.93 kg/(ha·a)].Of all the carbon fixation of different land-use types,greenhouse crop was the highest[16 283.70 kg/(ha·a)],followed by field vegetable[11 135.38 kg/(ha·a)],food and cash crop[10 694.70 kg/(ha·a)],orchard[5 234.00 kg/(ha·a)],urban green land[4 783.94 kg/(ha·a)],forest[4 364.11 kg/(ha·a)].Of all the net carbon sink of different land-use types,greenhouse crop was the highest[14 245.82 kg/(ha·a)],followed by field vegetable[9 374.02 kg/(ha·a)],food and cash crop[9 303.78 kg/(ha·a)],urban green land[4 433.18 kg/(ha·a)],forest[4 165.00 kg/(ha·a)],orchard[4 007.43 kg/(ha·a)].Of all the value of net carbon sink of different land-use types,greenhouse crop was the highest[13 120 Yuan/(ha·a)],followed by field vegetable[8 633 Yuan/(ha·a)],food and cash crop[8 569 Yuan/(ha·a)],urban green land[4 141 Yuan/(ha·a)],forest[3 836 Yuan/(ha·a)],orchard[3 691 Yuan/(ha·a)].The crop net carbon sink value was higher than trees,so it was suggested that the net carbon sink of crops should be incorporated into the ecological compensation system,to reduce the carbon input of crops,improve the quality of agricultural products,and give full play to the ecological function of cleaning air of crops.
