Abstract

Land consolidation projects (LCP) has been applied in various countries to decrease land fragmentation, to give field road and to create more appropriate regular parcel shapes besides many benefits to farmers. Moreover, LCP help to decrease the cost of irrigation system establishment. Türkiye aims to modernize open irrigation systems into pressurized systems with LCPs to save water due to climate change and global warming. However, previously published studies on the effect of LCP on designing pressurized irrigation network are not adequate. In this study, Eymir Village LCP in Türkiye was chosen as the material to investigate how can LCP affect the cost of the establishment of a pressurized irrigation system. In this context, two similation of irrigation systems are designed with help of geographic information systems (GIS) and are analyzed by COPAM (Combined Optimization and Performance Analysis Model) to optimize the hydraulic performance. Results show that land consolidation proved to be an effective tool to solve spatial problems related to improving the irrigation systems, technical problems related to the performance of the networks, and the equity of services (guaranteeing 98% satisfaction of users). And, it has the most important effect on the economic feasibility of pressurized irrigation network establishment whose cost can be decreased by 13.6% by LCP.

土地整理项目对有压灌溉系统设计和成本的影响：土耳其案例研究

土地整理项目（LCP）已在多个国家得到应用，以减少土地破碎化，提供田间道路，并创造更合适的规则地块形状，此外还为农民带来许多益处。此外，土地整理项目还有助于降低灌溉系统的建设成本。由于气候变化和全球变暖，土耳其希望将露天灌溉系统现代化为使用低洼地保护区的有压系统，以节约用水。然而，以前发表的有关低氯氯吡喃对设计有压灌溉网络的影响的研究并不充分。本研究选择土耳其埃米尔村低洼地作为研究对象，探讨低洼地如何影响有压灌溉系统的建设成本。在此背景下，利用地理信息系统（GIS）设计了两个模拟灌溉系统，并通过 COPAM（优化与性能分析模型）进行分析，以优化水力性能。结果表明，土地整理被证明是解决与改善灌溉系统有关的空间问题、与网络性能有关的技术问题以及服务公平性（保证 98% 的用户满意度）的有效工具。而且，土地整理对建立有压灌溉网络的经济可行性具有最重要的影响，通过土地整理，其成本可降低 13.6%。
