With global environmental changes and rapid industrialization、Urbanization process，Land resources are generally facing degradation、Empty waste and contamination issues，Restricting sustainable land use and sustainable agricultural development，Land consolidation projects have become an important means to solve these problems。However，People have had some misunderstandings dafabet mobile loginabout land consolidation for a long time，Some people think that land engineering does not have much technical content，For example, water conservancy project、Construction Project、Traffic Road Engineering、Ecological Protection Project，I can do it in any engineering industry，The main reason is that the core technology of land engineering has not been identified in the past，Failed to grasp the essence of the land issue。In fact，Soil reconstruction is the core foundation of land engineering，But for many years we have neglected the systematic research and engineering practice on this core issue。

Soil reconstruction is the prerequisite for improving land quality。The scientific research and engineering practice of soil reconstruction mainly include the survey of remediation objects、Material selection、Mechanical calculations、Construction of earth structures、Adjustment of soil chemical composition、Key links such as the deployment of biological nutrients，Is the basic prerequisite to ensure the quality of land in land consolidation projects。Shaanxi Land Engineering Construction Group Co., Ltd. (referred to as "Shaanxi Land Engineering") has completely implemented these key links in the land remediation of Mu Us Sandy Land，Preferred for the widespread local distribution of arsenic sandstone、Tight and dense “new material”，After years of research, a “land formula” that meets the physiological needs of different crops has been proposed，According to this, the arsenic sandstone and sand are accurately compounded to form soil，Constructing a healthy farmland system through the coupling of multiple elements of water, soil, air, human beings，Achieved the transformation of "two evils" into "one treasure"，Received water saving、Sand fixation、The comprehensive effect of increased efficiency。

The core of land engineering is soil reconstruction。The key is to build a suitable soil structure，Better serve the organic life forms carried by the soil，includes plants、dafabet loginAnimal、Microorganisms and humans。The reason why land consolidation in some areas is exposed、Two years of drought、Back to the same old appearance in three years”，The reason is that these renovation projects pay more attention to the leveling of the field surface、Supporting facilities、Landscape beautification，But the soil reconstruction that land engineering should have is ignored or weakened。In the process of land remediation in the Yangjuangou watershed in Pagoda District, Yan'an，Shaanxi geological construction based on soil exploration and structural analysis，Designed and built a moderate-scale water intercepting ditch，Cleverly solves the problem of land being difficult to cultivate due to waterlogging all year round。

Land consolidation projects must be tailored to local conditions、Emphasis on practical results。Regional soil general survey should be completed before preliminary design，Implement and refactor for specific problems、Complex、Land engineering technical measures upgraded to the main content，Effectively solve the coupling of land elements、Structural optimization、Global issues with function improvement。In the practice of comprehensive improvement and restoration of hollow villages in plain agricultural areas of Shandong，Shaanxi geological construction exploration proposes a "trinity" engineering technology system of soil mass-soil layer-soil quality，Gives newly created farmland a "healthy state" from the perspective of ecological civilization construction、The scientific connotation of “organism”，Promotes soil stability、Coordination and unification of structural rationality and functional efficiency。

Land engineering lays a solid foundation for the progress and spread of human civilization。Humanity’s future ideal is to make full use of space resources，Continuously expand the space for survival and development。NASA has launched cutting-edge exploration in this regard，They are trying to find soil on other planets in space，Discover the dafabet mobile loginbasis suitable for the existence of living things。Technological innovation and engineering practice of soil reconstruction，It can also provide reference for trying to build a soil that can satisfy human survival on other planets。In this sense，Research on soil reconstruction is an objective need for human beings to optimize land space and an inevitable choice to expand living space。
