Problems solved by technology

[0004] Since different desertified grasslands correspond to different restoration methods in subsequent restoration, and at the same time, different classification methods of desertified grasslands result in different grading results for the same grassland, resulting in different restoration methods for subsequent restorations, it is easy to make the actual situation of grasslands different from that of other grasslands. The classification results obtained do not match. After using the existing grassland restoration methods corresponding to each level of desertified grassland for treatment, the treatment effect is not good. At the same time, it leads to high investment in manpower and material resources, and in severe cases, the grassland desertification is more serious.

Embodiment 1

[0057] According to the method provided by the present invention, in different regions of the Uragai grassland, five samples are selected for each region, and the total coverage of the grassland in the summer and winter of the same year and the output of edible herbage in the aboveground part of the total aboveground part are monitored for each sample. For the percentage of grass yield, when in the same subregion, the annual variation rate of the total grassland cover of more than 90% of the samples is greater than 60%, and the average total grassland coverage is less than 10%, the subregion is excluded. Among the remaining samples, 10 test plots with different degrees of desertification obtained according to this method were selected, with a total area of ​​2000 mu, as shown in Table 1. The acquisition method of each sample refers to the national standard.

[0058] Among them, the herdsman Cao Lei’s family was treated in 2015, with an area of ​​186 mu, and the rest of the plot...

Embodiment 2

[0088] 10 mu of untreated test plot near Mazong Mountain was selected. The only difference between it and Example 1 was that it was graded according to the national standard and repaired according to the method provided in Example 1.

[0089] After one year of treatment in 2016, the results showed that the density in 2017 was significantly higher than that in 2015 and 2016 (P<0.05), the average coverage increased from 3.7 to 35.89, and the density in 2016 and 2017 was significantly higher than that in 2015 (P <0.05), meanwhile, compared with Example 1, the therapeutic effect of Example 1 is better.

[0090] To sum up, the grassland desertification grading method provided by the embodiment of the present invention makes reasonable adjustments according to the actual geographical conditions of the grasslands in Inner Mongolia, eliminates factors that are prone to errors, makes the classification more practical, and effectively improves the subsequent corresponding desertification...

Abstract

The invention relates to a grassland desertification classifying method and application thereof. The grassland desertification classifying method comprises partitioning a grassland, selecting multiplesamples from every partition, monitoring the total coverage of every sample as well as the percentage occupied by the aboveground edible grass yield from the total aboveground grass yield in the summer and the winter of the same year, and removing the partitions, of which the annual changes of the total coverage of more than 90% of the samples are higher than 60% and the average total coverage islower than 10%; when four or more monitored indexes meet the standard of a corresponding level of desertified grassland, determining the grassland to be a desertified grassland of the corresponding level; when five or more monitored indexes fail to meet the standard of a corresponding level of desertified grassland, determining the grassland to be an undesertified grassland. The grassland desertification classifying method and the application thereof enables classification to be more practical and effectively improve the efficiency and effects of subsequent corresponding desertification treatment.

Description

technical field [0001] The invention relates to the technical field of ecological protection, and in particular to a grassland desertification grading method and its application. Background technique [0002] Grassland is a type of vegetation, usually distributed in chestnut soil and chernozem areas with an annual precipitation of 200-300mm. It is a herbaceous plant community composed of xerophytic or medium-xerophytic herbaceous plants. The dominant plants are perennial clusters or rhizome types. Grasses and various weeds more or less drought tolerant. [0003] According to the biological and ecological characteristics, it can be divided into four types: meadow grassland, typical grassland, desert grassland and alpine grassland. Among them, the grasslands with sandy surface environment in different climate zones are affected by factors such as wind erosion, water erosion, drought, rodents and insects, and human improper economic activities, so that the natural grasslands a...
