Grassland soil degradation evaluation method

Abstract

The invention belonging to the field of the soil detection technology discloses a grassland soil degradation evaluation method comprising steps of evaluation target selection and recognition automation perfection, inputting of original data of a destination, partial evaluation of original data of the destination, evaluation of basic characteristics of the destination, evaluation of a homogeneity destination, and evaluation of a heterozygosity destination. Reference data evaluation is provided for adapting to the local agricultural environment and meeting the soil condition with the local agricultural ecological characteristics. The method can be used for guiding the crop types, varieties and production technology of the local agricultural ecological system. A basis is provided for controlling the ecological agriculture and intensified agriculture based on combination of the local ecological system and agricultural economy as well as for improvement of degraded agricultural soil erosion, so that the stabilization of the agricultural ecological system and stability of the agricultural environment concept are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of soil detection, and in particular relates to a grassland soil degradation evaluation method. Background technique [0002] The natural conditions of grassland in Xinjiang include climate, landform, soil, hydrology, etc., which are the basic conditions for the formation of grassland. Xinjiang is located in the northwest of my country. Its geographical location is between 73°40′-96°18′ east longitude and 35°40′-49°50′ north latitude. It is connected to Gansu, Qinghai and Tibet in the east and south respectively. It borders India, Pakistan, Afghanistan, the Soviet Union, and the People's Republic of Mongolia to the southwest and northeast, respectively. It is 1900 kilometers long from east to west. It is 1,500 kilometers wide from north to south, with a total area of ​​1.65 million square kilometers, accounting for about 1 / 6 of the total area of ​​the country. There are mountains, hills, plains, deserts, ...

AI Technical Summary

Problems solved by technology

[0006] Existing grassland soil degradation assessment techniques cannot provide evidence for serious grassland degradation that restricts the development of grassland animal husbandry and directly threatens the livelihood of herdsmen, and cannot provide reasonable suggestions for improving or restoring grassland soil nutrient status
