In view of the fact that the design of farmroad and canal
affects the efficiency of farm utilization, this study proceeds
the computer-aided design for land readjustment of planning and
design for farmroad and canal of farm land consolidation. The
study aim at simulating operation of planning and design for
farmroad and canal engineering in consolidation area, and
utilizes the established geographic database from Geographical
Information System (GIS) to inquiry the numerical value
topography and the aforementioned attributive and spatial
distributed data of the consolidation area. As to the
attribution of each polygon, this system will compute its area,
perimeter, and record its basic attribution in the data list.
It can be the reference for the district division. To be
adapted to the water distribution project in rotational
irrigation, the design of consolidation area takes tertiary
block as a basic unit, moreover, to establish the design flow
of arrangement of farmland block, and we can divide the
operation model into "Direct Land Readjustment Model" and "Land
Readjustment Model After Tertiary Block Divided", models each
land readjustment on the same consolidation area, separately,
proceed the analyze and arrangement of land readjustment in
deformed block, and draw the result of farmland block in
computer. This study suggests the Direct Land Readjustment
Model is preferred to the farm land consolidation in
unconsolidation land, its operation steps are land readjustment
first, the differentiate tertiary block. However, Land
Readjustment Model After Tertiary Block Divided is preferred to
the consolidation area which is consolidated at early time, and
is to renew its farmroads and canals, the operation steps are
to differentiate tertiary block first, then land readjustment
at each tertiary block. It is the target of this study that
utilizing information management and utilization computer-aided
system to assist proceeding of consolidation work and raise
efficiency
