【摘要】 依据生产生态足迹理论,以衡量作物生产过程中资源占用情况为目的,提出了作物生产生态足迹的概念,并确立了量化模型与评价方法。选取江苏省7种作物进行生产生态足迹核算,分析作物在生产过程中生态占用和资源利用情况,同时核算万元GDP生产生态足迹以反映资源利用效益。结果表明:土地资源对作物生产生态足迹的影响是最大的;人均作物生产生态足迹由低到高依次是花生、籼稻、棉花、玉米、油菜、粳稻、小麦,作物万元GDP生产生态足迹从低到高依次为花生、粳稻、籼稻、棉花、玉米、小麦、油菜。评价结果显示生态足迹是一种衡量不同作物生产系统中资源利用情况和环境污染状况的好方法。更多还原

【Abstract】 the study based on the productive ecological footprint theory,for the sake of measuring the usage of resource during the production process.The concept that the productive ecological footprint of crops(PEFC) was put forward and the quantitative model and evaluation method were established.Seven crops in Jiangsu province were selected for the evaluation in order to analysis the usage of resource and the environmental pollution actuality,meanwhile,the productive ecological footprint per ten thousand Yuan GDP was also accounted according to reflect the resource utilizing efficiency.The results showed that: Arable land occupation was the most influential factor in PEFC;the PEFC per capita from low to high were peanut,hsien rice,cotton,maize,rape,japonica,wheat;the productive ecological footprint per ten thousand Yuan GDP from low to high were peanut,japonica,hsien rice,cotton,maize,wheat,rape.Finally,the result scientifically and objectively showed that the PEF was a good method to measure resources utilization and environmental pollution in various crops production systems.更多还原
