A Method for Estimating the Reasonable Burial Depth of Groundwater in Artificial Forest

Abstract

The invention discloses a method for estimating ground water reasonable buried depth of a planted forest and belongs to the technical field of intersection of the forestry ecological project technology and the environmental monitoring technology. The method includes the following steps: determining a plurality of ground water sampling points in small areas representing different landforms, soils, plants and growth condition backgrounds of planted forest areas in the different areas of the planted forest, measuring actual ground water buried depth of the ground water sampling points, collecting plant types and growth condition grade of the plants that the ground water sampling points correspond to, acquiring a group of ground water reasonable buried depth ensuring normal growth of the plants under the ground of specified sample areas according to the collected information and further estimating the ground water reasonable buried depth of the planted forest. The method provides a new model and a new way for quantified checking of the ground water buried depth under the background of planted forest and provides reasonable effective accordance for sustainable management of the planted forest.

Description

technical field [0001] The invention relates to a method for estimating the reasonable burial depth of artificial forest groundwater, which belongs to the technical field intersecting forestry ecological engineering technology and environmental monitoring technology. Background technique [0002] The buried depth of groundwater refers to the distance from the groundwater surface to the ground, and the commonly referred to as groundwater refers to diving. There is also stagnant water and confined water underground. Submerged buried above the first stable aquitard below the surface, gravity water with a free surface. The free surface of diving is called the diving surface, the absolute elevation of the diving surface is called the diving table, and the distance between the diving surface and the ground is called the diving depth, that is, the buried depth of groundwater. It is generally buried in the pores of Quaternary loose sediments or in the cracks of the bedrock exposed...

Problems solved by technology

At present, the research on groundwater depth is carried out under the existing ecological system and ecohydrological conditions. When analyzing the groundwater depth of a watershed or region, the most suitable groundwater level and reasonable groundwater depth must be considered. Our monitoring The surveyed groundwater depth is often the status quo, which is different from the reasonable groundwater depth. The reasonable groundwater depth is closely related to the surface cover, ecological structure and function, which further increases the complexity of estimation.
