Technical Field

The invention relates to the field of ecological restoration, in particular to an ecological restoration method based on homeland improvement planning.

Background

The land reclamation refers to a general term for surveying, planning, developing, utilizing, improving, treating, protecting and other measures of the business land according to the agricultural ecological balance principle and the national economic plan requirements. The method scientifically treats the agricultural land, is beneficial to reasonably developing and utilizing agricultural land resources, improves the land utilization rate, keeps ecological balance, and prevents water and soil loss, soil desertification, alkalization and the like. Various engineering measures adopted in the agricultural land improvement process, such as surveying and mapping, farmland water conservancy, agricultural machinery, remote sensing technology and the like, are called agricultural land improvement engineering. The basic meaning of homeland improvement. The target tasks of homeland improvement mostly include the following 3 aspects: the method has the advantages of promoting regional economic development, promoting regional balance and restoring ecological environment.

From the international visual field and development history, the concept of homeland remediation can be expressed as follows: and in order to integrally improve the territorial space elements and the system to meet the new functional requirements, the territorial is modified and constructed according to the territorial space planning and the related planning. This concept includes the following 3-layer meanings:

firstly, the whole improvement of the territorial spatial elements is to improve the territorial spatial structure and functions of the whole elements of the mountain-water forest field, the lake, the grass, the village and the village by adjusting the relation between people and the ground, optimizing the spatial structure, coordinating the regional development, guaranteeing the ecological safety and the like. The system meets new functional requirements, namely the requirements of ever-increasing production, life and ecology of human beings and the requirements of survival and happiness of human beings, which are the starting point and the aim of promoting the homeland improvement of human beings and solving the problem of 'why' to do. The integrity and systematicness are important characteristics that the land improvement is different from the general single improvement such as farmland improvement.

In a broad sense, single improvement such as farmland improvement can also be included in the field of homeland improvement, but the single improvement is not a main body of homeland improvement, and the difference between the 'homeland' and the 'land' is also the difference.

Secondly, the core of homeland improvement is reconstruction. According to the requirements of nature, society, economy, ecology and culture laws, the method comprehensively utilizes measures such as development, arrangement, reclamation, restoration and protection to carry out structural optimization and reconstruction construction on the homeland space so as to improve the efficiency, quality and overall function of the homeland space. This is a problem of "how to do" and to what extent.

Thirdly, the transformation and construction is an engineering activity, and the main targets and contents of the transformation and construction are to adjust the human-ground relationship, improve the quality of the soil space, improve the efficiency of the soil space, control the soil space environment, construct the life community of the mountain and water forest fields, lakes and grasses and promote the sustainable development of the area. It is one option for humans to seek symbiosis with the earth.

When the meadow of desertification is restoreed, generally through the comparatively flourishing plant of planting root system, carry out the solid through its flourishing root system to gu soil and reduce the effect of the loss of soil and water, but, the serious region of general soil and water loss when reforming, because soil property desertification, it is loose, lead to the root system of plant hardly to prick the root, lead to when planting the plant and carry out ecological remediation, the survival rate of plant is lower, cause holistic restoration cost high, and repair efficiency is not high.
