Problems solved by technology

Although this method solves the water problem, it does not use and transform the river beach or sandbar on this basis, which not only wastes precious land resources, but also adversely affects the local natural landscape and ecological environment.

Embodiment

[0111] Taking a project in the Longmen section of the Yellow River in Shaanxi as an example, the project area belongs to the semi-arid continental monsoon climate in the warm temperate zone, with an annual average precipitation of 555.2mm, mainly concentrated in summer and autumn, with an average precipitation of 306mm from July to September. The average temperature for many years is 13.7°C, and the average daily temperature range is 10.3°C throughout the year. The accumulated temperature of ≥10°C is 4626°C, which lasts for 209 days, which is significantly better than the upper limit index of warm temperate zone (accumulated temperature of warm temperate zone is 3400°C-4500°C); the accumulated temperature of ≥20°C is 2718°C, which lasts for 107 days. The annual average sunshine is 2436 hours, and the total solar radiation reaches 121.24kcal / (cm 2 ·a), the average frost-free period for many years is 208 days. The average air pressure for many years is 96.3×10 3 Pa, the annual...

Abstract

The invention discloses a land engineering design method comprising the following steps: S1, investigating the climate conditions and water resource conditions of a region to be treated; S2, making an on-the-spot survey and an indoor analysis; S3, choosing a plurality of crops which can be planted according to the investigation results of S1 and S2, calculating the water supply capacity of the region and the amount of water needed for crops, checking water conservancy conditions, and determining a crop to be planted; and S4, reconstructing the soil of the region to be treated and improving the fertility of the soil. According to the method, the bottom layer of a river course, bottomland or sandbank is plowed and a plough layer is constructed, the physical and chemical properties of the soil are improved effectively, the soil fertility is improved, the risk of soil erosion is reduced, and land desertification is inhibited. By integrating the water and soil resource advantages of river course, bottomland or sandbank, the utilization rate and productivity of land resources are improved, and the effective area of cultivated land is increased.

Description

technical field [0001] The invention relates to the field of land improvement engineering, in particular to a design method of land engineering. Background technique [0002] my country's per capita arable land resources and arable land reserve resources are few, and the quality of arable land has seriously degraded. In 2016, the Central Document No. 1 emphasized adhering to the most stringent arable land protection system and adhering to the red line of arable land. Implement and improve the balance system of cultivated land occupation and compensation, insist on occupying more and supplementing more, occupying good and supplementing good, occupying paddy fields and supplementing paddy fields. In order to respond to the call of the national policy and add cultivated land resources to the country, it is an effective way to develop the unused and difficult-to-use land by using soil reconstruction technology. [0003] For the sedimentary wandering rivers along the Yellow Riv...
