黄土台塬区土地生态化整治工程建设——以宝鸡市陇县土地整治项目为例

Land ecological consolidation in Loess Tableland area——A case study of the land consolidation project in Long county,Baoji City

中国土地整治已从传统的以增加耕地有效面积为目的向耕地数量、质量和生态并重转变。土地生态化整治是实现人-地-环境和谐共处的重要手段。本文通过归纳整理国内外土地生态化整治的发展及内涵,提出基于耕地占补平衡的土地生态化整治应遵循增加耕地有效面积并提高耕地质量、增强土地抵御自然灾害的能力、保持自然景观性、提高民众参与度和社会可接受性的四项原则,同时选取黄土台塬区耕地后备资源整治项目作为研究对象,从生态田块设计、生态道路工程及灌溉排水工程设计等方面,进行土地生态化整治设计的实证研究,从而推动土地生态化整治技术在我国主要耕地资源后备区域实践中的应用与发展。

The traditional conception of the land consolidation in China has been upgraded from simply aiming to increase the actual land for cultivation to laying equal stress on arable land quality,quantity and ecological environment.Land ecological consolidation is an important method to realize the goal of human-land-environment in harmony.This article takes reviews on the development history of the land ecological consolidation, both domestically and internationally.It upholds the ensuing four principles for land ecological consolidation based on the cultivated land requisition-compensation balance,shall strive to increase the arable farmland areas as well as enhance the quality of the cultivated land.Secondly,the land's resistance against the natural disasters needs to be further consolidated.Thirdly,the natural landscape must be maintained at its best.Lastly,the social acceptance and the citizens' participation must be taken into consideration when it comes to the implementation of the land consolidation.In this regard,the article chooses Weibei Taiyuan land consolidation reserve(land consolidation project in Lan Jiabao,Baoji city)as the research object,to elaborate the ecological land consolidation frommultiple perspectives,e.g.land designing,ecological roads pavement,irrigation and drainage engineering.It is the author's hope that this article may contribute to the promotion of the application and development of the ecological land consolidation technologies,especially in the area of the reserved land for cultivation.
