| Summary: | 碩士 === 國立中興大學 === 農村規劃研究所 === 94 === Since the farm roads and waterways in the farmland consolidation areas
on early days could not meet the requirements for modern agricultural
management, the government implemented a “Project of Renovating and
Improving the Farmroads and Waterways in the Previous Farmland
Readjustment Areas” in 1988. Transportation convenience of the farm roads
and efficiency of the waterways were emphasized. Durability and stability of
the structural materials were taken into consideration. Consequently, farm
roads were straightened, broadened and paved with gravel and the waterways
were constructed into U-shaped ditches made of concrete. Though the
requirements for modern agricultural management were met; however, the
ecological environment in the rural areas was not maintained causing the loss
of the ecological function of the corridors of the farm roads and waterways.
Accordingly, innovations and improvement on the farm roads and
waterways in the previous farmland readjustment areas applying
eco-environment planning and design became the subject of this study. The
performance of carrying out projects for renovating and improving the current
farm roads and waterways and the problems derived as well as their functions
of maintaining the ecological environment were investigated. Theories of
eco-environment planning and design were generalized and integrated to
establish the evaluation factors and the resistance weights. Next, a
questionnaire survey was conducted and analyzed for the selection of the
criteria and their weights for innovation and improvement of the farm roads
and waterways applying eco-environment planning and design. Combination
of the evaluation criteria and a quantified calculation model, including the
resistance weights and the travel cost of the corridors of the farm roads and waterways revealed the changes of the resistance weights and the travel cost
before and after renovating and improving the farm roads and waterways in
the previous farmland consolidation area in A-dan (4). Influential factors
were further investigated so as to serve as a reference for future planning and
design and related studies on innovation and improvement in farm roads and
waterways.
It was found that the travel cost of corridors increased before and after
improving the farm roads and waterways in the farmland readjustment area in
A-dan (4). Two criteria, the pavior (pavement material) on the farm roads and
the width of the separation zone, played the most significant role for the
increase in the travel cost of the corridors. As for the waterways, design of the
ditch gradient and the material used for the ditch were two most important
factors.
