Problems solved by technology

When describing the status quo of the buried depth of groundwater in a region, people hope to use an average buried depth to reflect the state of the groundwater in the region. Currently, the Thiessen polygon method is usually used to calculate the regional average value, but this method only studies the dynamic changes of groundwater. Applicable to areas with large areas and many influencing factors, it is no longer applicable to small oasis areas with relatively closed material circulation
The reason is that there is a strong correlation between the factors affecting the buried depth in the area, which makes the error of the constructed model larger and the obtained groundwater buried depth data is inaccurate

Embodiment

[0082] The Cele Oasis in the central part of the southern margin of the Tarim Basin was selected as a typical research area, relying on the long-term monitoring data of the National Field Scientific Observation and Research Station of the Cele Desert Grassland Ecosystem (hereinafter referred to as the Cele Station). From the perspective of the total water demand of the oasis, considering the profit and loss relationship between the total ecological and agricultural water demand in the fan-shaped area of ​​the Cele oasis and the water supply of the oasis, the dynamic change of groundwater depth under the influence of the water demand of the oasis is obtained.

[0083] The groundwater depth data come from the groundwater depth data collected from 25 long-term fixed groundwater observation wells established by the Cele Station in the Cele Oasis, and use this data as a starting point to monitor the oasis water use.

[0084] The sum of the ecological water demand and the agricultura...

Abstract

The invention discloses an inland arid area oasis water resource monitoring method and system. The method comprises the steps of obtaining the total water demand of oasis in the inland arid area, wherein the total water demand comprises the ecological water demand and the agricultural water demand; obtaining annual average runoff of the water resource supply river; obtaining the quantity of underground water to be pumped according to the annual average runoff and the total quantity of required water; according to the to-be-pumped underground water amount, determining the water level descendingheight; obtaining the average burial depth of underground water; and determining the current underground water burial depth according to the water level descending height and the average undergroundwater burial depth. By means of the method, the current underground water burial depth can be accurately obtained, and therefore effective observation of oasis water resources in the inland arid areais achieved.

Description

technical field [0001] The invention relates to the field of monitoring oasis water resources, in particular to a method and system for monitoring oasis water resources in inland arid regions. Background technique [0002] Oasis is an important ecosystem in the arid region, with unique man-land relationship and natural landscape. The oases in Xinjiang and Gansu are the main areas for scholars to study. The research focuses on the rational allocation of water and soil resources in oases, ecological water demand, oasis agricultural development, ecological environment construction, urban development characteristics, and ecological economic systems. Since water resources are the most important limiting factor for the development of oases and directly determine the existence and development of oases, the discussion of oasis water resources cannot be avoided when studying oasis issues. In recent years, the economy of the oasis area has experienced rapid development and transforma...
