Soil environment quality monitoring method

Abstract

The invention discloses a soil environment quality monitoring method. The method comprises the following steps: 1) taking a to-be-monitored zone as a scope, uniformly dividing a target land type layer in a geographic information system into a plurality of rectangular grids, and taking central points of the grids, main land types of which are target land types, as initial monitoring point positions; 2) according to a present land use situation, performing position adjustments on the initial monitoring point positions until the land types of the initial monitoring point positions acquired in the step 1) are the target land types; 3) for the same grid, replacing the initial monitoring point positions with recent historic monitoring point positions as monitoring point positions; according to the land types, performing adjustments on the monitoring point positions until the monitoring point positions cover soil types of main target land types; and taking the monitoring point position after the adjustments as monitoring points of target lands. The method disclosed in the invention uses the GIS special analysis technology, improves soil environment quality monitoring accuracy and representativeness, optimizes the number of cultivated soil environment quality monitoring distributed point, and is easy to operate and implement.

Description

technical field [0001] The invention relates to a soil environmental quality monitoring method and application, and belongs to the fields of soil science and environmental science. Background technique [0002] With the rapid development of industrialization and cities, the area of ​​cultivated land, forest land and other land that affects environmental quality has decreased sharply, especially cultivated land. The per capita cultivated land area in my country is less than 1 / 2 of the world average. How to keep the red line of 1.8 billion mu of cultivated land in my country is worrying; At the same time, industrial activities and environmental pollution have intensified, leading to a sharp drop in the soil quality of cultivated land, affecting the quality of agricultural products and threatening human health. [0003] As the basis for solving the above problems, how to monitor the soil has been widely studied in this field for many years. The above-mentioned monitoring proces...
