项目摘要

Symbiosis is defined as heterogeneous coexistence. In respect to the human attitude or response nature, there exists two opposite ideas; that is “manipulation of nature" and “subjection to nature". Human symbiosis with nature (HSN) is considered as the coexistence of these opposing ideas. Applying a fuzzy concept set to express this coexistence, we can find a way to develop an index of HSN. When μ is the membership function of the fuzzy set concerning HSN, μ=0 for “subjection to nature", with μ=1 for “manipulation of the nature", and 0<μ<1 for the intermediated zone.To develop the index of HSN concerning technologies, we set five ranks; A〜E according to the smaller number of μ. We selected four cases of technologies from the basin of the Chikugo River to assess the rank of each technology. Next we deduced estimated membership functions (φ), where the independent variables are capital coefficients, the rate of energy input, and the rate of artificial materials input. Using these φs, reversely we can calculate HSN. We used this formula to estimate HSN in the basin of the Chikugo River.To refine this research, we have to collect more data necessary to assess and estimate HSN. We, however, may not have enough time or budget, because of rapid changes in society and economic conditions. To cope with these circumstances, we developed a method which enables us to assess and make decisions under conditions of insufficient data and time. In this respect, the fuzzy logic method is also useful. Finally we imply that the methodology of cultural economics corresponds to the implementation of policies derived from this research.

共生被定义为异质共存。关于人对自然的态度或反应，存在着“操纵自然”和“服从自然”两种对立的观点。人与自然的共生被认为是这两种对立思想的共存。应用模糊概念集来表达这种共存，我们可以找到一种方法来开发HSN指数。当μ为人类安全感模糊集的隶属函数时，μ = 0表示"服从自然"，μ = 1表示"操纵自然"，0 <μ <1表示"中间地带"，为了发展人类安全感的技术指标，我们设置了五个等级，根据μ的较小值，A为最小值，B为最大值，C为最小值，D为最小值。我们从筑后川流域选择了四个技术案例，以评估每种技术的排名。其次，我们推导了估计的隶属函数（φ），其中自变量是资本系数，能量输入率和人工材料输入率。使用这些φ s，φ s，我们可以计算HSN。我们用这个公式估算了筑后河流域的HSN。为了完善这项研究，我们必须收集更多的必要数据来评估和估算HSN。然而，由于社会和经济条件的迅速变化，我们可能没有足够的时间或预算。为了应对这些情况，我们开发了一种方法，使我们能够在数据和时间不足的情况下进行评估和决策。在这方面，模糊逻辑方法也是有用的。最后，我们暗示，文化经济学的方法对应于从本研究中得出的政策的实施。
