Abstract

The invention relates to a method for analyzing a soil pollution spatial distribution rule based on a geographic information system technology. The method comprises the following steps of: collecting related spatial data information of an area, and constructing a basic spatial information database by stratified digitalization; acquiring coordinate information of a field sampling point by a handheld GPS (global position system) receiver, processing acquired field images, testing to obtain soil pollution data indexes, and constructing a soil pollution attribute database; configuring the sampling point to the basic spatial information database according to the acquired coordinates of the sampling point; and carrying out interpolation treatment on different models according to a constructed interpolation model library, and selecting an optimal interpolation model to obtain a soil pollution distribution diagram and a soil pollution evaluation ranking diagram. The method provided by the invention has important practical meanings on guiding the agricultural production, controlling the soil pollution, promoting the sustainable agricultural development, and the like.

Description

[0001] Technical field [0002] The invention involves an analysis method for soil pollution, especially a method that analyzes the laws of soil pollution space based on geographical information system technical analysis. Background technique [0003] Soil is the material basis for life to survive, and it is an indispensable and renewable natural resource for human beings.All human activities are inseparable from the soil.With the development of productive forces, the continuous increase in the world's population, the increasing production activities that people engage in, and the disturbance and destruction of the natural ecosystem, especially the pollution caused by the soil, is gradually increasing.In agricultural production, in order to pursue food production, the amount of fertilizer and pesticides continues to increase, and the soil as an important part of the environment is facing an increasingly serious impact.According to relevant literature reports, my country's annual ...
