Construction of the ecological footprint calculation system from the viewpoint of the ecosystem service

生态足迹指数是将生态系统服务的消耗与人类活动对土地资源的消耗面积进行交换的指标。公司的活动是主要的人类活动，利用指示公司活动的指数组将其转换为EF指数。生态足迹指数是将耕地面积作为粮食生产，草地面积作为畜牧业用途，森林面积作为木材和纸张用途，森林面积作为碳汇，抑制区作为房屋建筑和城市基础设施(道路和火车等)的总和来计算生态系统维护。这些指数与公司活动和人类活动使用的ESS和EF相关。在这项研究中，重新定义了公司活动和人类活动的ESS消耗，并列出了ESS的定义和具体实例，并对公司活动和人类活动进行了量化。例如，对于需要种植粮食的农田，通过家庭经济调查统计计算人均粮食消耗量，并将土地生产力的一个基本单位乘以消耗量。并且是经过计算的。通过统计或现有文献对生态系统服务的供给服务、调节服务、文化服务和基地服务进行了调查，构建了生态足迹指数测算体系。

The ecological footprint(EF) index is an index to exchanging the consumption of the ecosystem service(ESS) with human activities to the consumption area of land resources. The activity of the company which is main human activities are converted into an EF index utilizing index group indicating the activity of the company. The action to an instruction of the company activity for the natural symbiosis society realization and the offset activity (biological diversity offset) contribute to the ecosystem maintenance of the e earth.The current EF index is culculated as summation of the cultivated land area as the food production, the meadows area as the live stock farming use, the forest area as a timber and paper use, the forest area as the carbon sink, and the inhibition area as house construction and the city infrastructure(road and train etc). These index were linked with ESS and EF that company activity and human activities used. In this study, the ESS consumption of the company activities and human activities were redefined for an EF index.A definition and specific examples of ESS were listed and quantified company activity and human activities. For example, about farmland which is need to bring up the crops for food, the consumption of the food item was calculated per person by household economy survey statistics and multiplied a basic unit of the land productivity by the consumption. and was calculated. The ecosystem service such as the supply service, the adjustment service, the cultural service and the base service, was investigated by statistics or existing documents, then the EF index calculation system was constructed.
