项目摘要

This study aimed to identify issues to be discussed to realize local-scaled recycling systems of organic materials in urban fringe landscapes by examining three major issues as follows.1.Small-scaled material cyclic system between urban and rural land uses in urban fringe landscapesA novel evaluation framework of farmlands in a rural-urban mixed area was developed towards a sustainable agricultural system. The object of the framework was to establish a material circulation system that utilizes kitchen waste from houses to fertilize nearby farmlands. The framework was then applied to Kokubunji City in the Metropolis of Tokyo, a representative rural-urban mixed area. The framework illustrated that the degree to which farms may obtain sufficient compost is a factor of the size of the farms and their interspersing rate. The smaller the farms and the more interspersed they are, the greater the sufficiency of compost is. Meanwhile, farm products in small-scale farmlands with sufficient compo … More st satisfy the demand of those households providing kitchen waste.2.Effective interactions of consumers and farmers in a recycling system between urban and rural land uses in urban fringe landscapesAttempts to create effective recycling systems have encountered difficulties in fostering cooperation between groups of consumers and farmers. This is because of a lack of trust between both groups. For example, farmers do not trust unknown consumers to make good-quality compost. The objective of this research is to assess how willingly farmers and consumers cooperate with each other. This will enable policy-makers to understand how a recycling system can be made more effective. We argue that location has an important role to play in building trust. Overall the results show the importance of locating close to farmer's activity.3.Optimum maintenance schemes of satoyama in urban fringe landscapes to enhance biomass productionSatoyama woodlands located in urban fringe areas have lost their economic viability to be maintained and thus been abandoned for decades. However, recent attention on the biomass as an alternative renewable resource restored public attentions on satoyama, which may become one of indispensable sources of biomass. The aim of this study is to estimate the potential amount of biomass provided by satoyama according to several maintenance schemes. The study estimated that 1.22t/ha to 5.22t/ha of biomass, which can be transformed into electric power for 1,300 to 5,200 households, will be provided annually if an appropriate maintenance has been conducted.

本研究旨在通过对以下三个主要问题的研究，确定实现城市边缘区景观有机物质局部循环系统需要讨论的问题：1.城市边缘区城乡土地利用之间的小尺度物质循环系统一个新的评价框架，用于评价城乡混合区农田的可持续农业系统。该框架的目标是建立一个物质循环系统，利用家庭的厨房废物为附近的农田施肥。然后将该框架应用于东京大都会的科库邦寺市，这是一个典型的城乡混合区。该框架表明，在何种程度上，农场可以获得足够的堆肥是一个因素的大小的农场和他们的散置率。农场越小，分散的越多，堆肥的充足性就越大。同时，小规模农田的农产品， ...更多信息 st满足那些提供厨房垃圾的家庭的需求。2.消费者和农民在城市边缘地区城乡土地利用之间的回收系统中的有效互动建立有效回收系统的尝试在促进消费者和农民群体之间的合作方面遇到了困难。这是因为两个群体之间缺乏信任。例如，农民不相信不知名的消费者能生产出高质量的堆肥。本研究的目的是评估农民和消费者之间的合作意愿。这将使决策者了解如何使回收系统更有效。我们认为，位置在建立信任方面发挥着重要作用。总的来说，结果表明，靠近农民的活动的重要性。3.城市边缘景观中的里山最佳维护方案，以提高生物质生产位于城市边缘地区的里山林地已经失去了经济可行性，以保持，因此被遗弃了几十年。然而，近年来生物质作为一种可替代的可再生资源的关注恢复了公众对里山的关注，它可能成为生物质不可或缺的来源之一。本研究的目的是根据几种维护方案来估计里山提供的潜在生物量。该研究估计，如果进行适当的维护，每年将提供1.22吨/公顷至5.22吨/公顷的生物质，可转化为1，300至5，200户家庭的电力。少
