Academicians of the two academies talk about land engineering

Land engineering is the use of engineering technology to solve land use problems，Convert unused land into usable land or make efficient use of used land，The process of actively coordinating the harmonious development of the relationship between man and earth。Land engineering discipline as the discipline support of land engineering，It is a new one、Interdisciplinary comprehensive disciplines，It is an applied discipline that uses systematic discipline principles and technical systems to thoroughly solve land engineering construction and management problems。

————Excerpted from "Introduction to Land Engineering"

Sun Honglie (Academician of the Chinese Academy of Sciences)、Former Vice President of the Chinese Academy of Sciences)

At present, soil erosion is still very serious in our country，Land engineering is the main means and method to effectively dafabet mobile appalleviate soil erosion，We are working hard to solve this problem。Through land reclamation、Comprehensive methods such as development，Realizing rational utilization of land resources、Improve land utilization，Increase the total area of ​​cultivated land、Achieve dynamic balance of total cultivated land、Control soil erosion，The purpose of protecting the ecological and natural environment。

Shen Guofang (Academician of the Chinese Academy of Engineering、Former Vice President of the Chinese Academy of Engineering)

I strongly support the establishment of a new discipline of land engineering。I think land projects should have the same status as water conservancy projects，To become a first-level subject in subject classification。The emergence of this discipline meets the needs of the times，I hope everyone can work together，Building a complete system of land engineering to create research and enrichment，Contribute to our country’s construction of an ecological environment and a beautiful China。

Shi Yulin (Academician of the Chinese Academy of Engineering)

The development of land engineering is of groundbreaking and historic significance。I am very happy to see that Shaanxi Land Engineering Construction Group is doing land engineering science，This is a wish of our land resources workers，Because land engineering is necessary to transform productivity，Sincerely hope that the land project can develop、Growing up，Formation of macroclimate。

Shan Lun (Academician of the Chinese Academy of Engineering)

The land engineering link was relatively weak in the past，The importance is now highlighted，First, there is social demand，The second is technological progress。Shaanxi Land Engineering Construction Group has done a lot of work in the rational utilization of land，Also achieved many results。I hope Shaanxi Land Engineering Construction Group will continue to take advantage of cooperation with all walks of life，Better development of land resources、Land transformation、Use the service。

Mao Zhi (Academician of the Chinese Academy of Engineering)

I gained a lot from this inspection in Shaanxi，I am fortunate to learn about the progress of land engineering research and discipline construction in my country，I feel it is eye-opening，Hope to continue to strengthen exchanges and cooperation in the future，We also look forward to organizing our laboratory personnel to come to Shaanxi for inspection and study as dafabet loginsoon as possible。Especially seeing the construction of the Network Remote Sensing and Information Center of the Ministry’s Key Laboratory，Very helpful to us，Let us be inspired。

Sun Jiulin (Academician of the Chinese Academy of Engineering)

The book "Introduction to Land Engineering" written by researcher Han Jichang of Shaanxi Land Engineering Construction Group has been published，Contains the basic theory of land engineering and further elaborates as needed，We very much support the establishment of the land engineering discipline。But there is still a long way to go to complete the construction of the land engineering discipline，It depends on the efforts of all of us here，Hope to develop as soon as possible，Used for technological innovation in land reclamation。

Wang Hao (Academician of the Chinese Academy of Engineering)

Land engineering is a national strategy，The party and the government have always attached great importance to the role of land engineering in ensuring national food security，Important role in promoting comprehensive economic and social development，This also brings us a rare development opportunity。With the dwindling land resources and the country’s increasing emphasis on land engineering construction，Fundamentals of Land Engineering Technology、Theoretical research is increasingly important，Achieving efficient land resources、Continuous、Scientific utilization is urgent。

Lei Zhidong (Academician of the Chinese Academy of Engineering)

This model is successful in Lubotan, Shaanxi Province，Worth promotion。Saline-alkali land as an important part of land engineering research，"Change discharge into storage、Coexistence of water and land、Saline-alkali land management for "harmonious ecology"，Give full play to the "convection-dispersion" effect of water and salt migration，Breaking through the traditional model of salt washing and drainage, which consumes a large amount of fresh water resources，High governance costs，Problems such as high later management and maintenance costs。

Fu Bojie (Academician of the Chinese Academy of Sciences)

The scientific research team led by researcher Han Jichang of Shaanxi Land Engineering Construction Group is based on the summary of everyone’s past practices in scientific research and engineering technology，Preliminarily proposed a framework system for the land engineering discipline。I think the introduction of the concept of land engineering is a breakthrough，It has dafabet mobile loginrigorous connotation and denotation，So we say that expanding land engineering into land science and engineering and making a breakthrough from the engineering category is a desirable way。

Nan Zhibiao (Academician of the Chinese Academy of Engineering)

After coming to Shaanxi this time, I feel that it is a worthwhile trip，Learned a lot。After several days of inspection in Shaanxi，See with my own eyes the achievements of Shaanxi Land Engineering Construction Group in land consolidation，This is also the first time involving corporate scientific research，I truly understand what the country says: Enterprises are the main body of innovation。Shaanxi Land Engineering Construction Group leads the country in innovation。Sincerely support the establishment of land engineering discipline，Hope to jointly promote the development of land engineering。
