Problems solved by technology

[0003] The impact of grassland degradation on the environment is particularly severe. The existing methods for collecting and processing grassland degradation information are too simple and have low applicability
However, there are many river valleys in my country, and the ordinary grassland degradation information collection and processing methods cannot conduct reasonable analysis for the more complex terrain in river valleys, the data is inaccurate, and the results of data processing are low in accuracy and reliability, and cannot be applied to river valley grasslands. manage

Embodiment 1

[0040] The following is the specific implementation process of the present invention in Ili River Valley, Xinjiang, my country.

[0041] The Yili River Valley is located in the northwest of Xinjiang, on the border of the motherland. Due to its special topographical features, it can intercept the moist water vapor brought by the land westerly, making it the largest oasis in Xinjiang and an important water source for the transnational river Yili River. Abundant precipitation creates favorable conditions for vegetation growth. Grassland develops in the Yili River Valley, which is the most widely distributed land cover type in the region, providing an important guarantee for regional biodiversity protection, water conservation and ecological balance maintenance. At the same time, the high-quality grassland resources in the valley also make it a famous pastoral area in the country. However, with the economic development and population increase in the Yili River Valley, the disturba...

Abstract

The invention discloses a data acquisition and analysis method for river valley grassland degeneration conditions. The method specifically comprises the following steps of: NDVI data obtaining, DEM data obtaining, information processing, data conversion, vegetation coverage inversion, grassland degeneration grading, grassland degeneration cold / hot spot analysis, grassland degeneration temporal andspatial variation analysis, grassland degeneration cold / hot spot distribution and evolution, river valley grassland degeneration altitude differentiation, grassland coverage analysis and grassland degeneration factor analysis. Through a grassland degeneration grading map, the method is capable of integrally analyzing areas with obvious grassland degeneration grades in tested areas, so that the data analysis is more intuitional; cold / hot spot analysis indicates that the spatial difference between grassland degeneration and improvement is more obvious; through grassland coverage analysis, degeneration features of grasslands with different coverage grades can be quantitatively analyzed and expressed; and through analysis of climate temperatures, rainfall capacities and grazing conditions, the analysis of the grassland degeneration conditions is more correct.

Description

technical field [0001] The invention relates to the technical field of grassland degradation and improvement, in particular to a method for collecting and analyzing information and data of grassland degradation in river valleys. Background technique [0002] Under irrational use, the process of retrograde succession and productivity decline of grassland ecosystems is called grassland degradation, also known as grassland degradation. The main manifestations are the decline of the height, coverage, yield and quality of grassland vegetation, the deterioration of soil habitat, and the decline of production capacity and ecological function. The long-term and large-scale grassland degradation not only causes the decline of the productivity of the grassland itself, but also causes the deterioration of the ecological environment and threatens the survival and development of human beings. Under the influence of unfavorable natural factors such as drought, wind and sand, water erosio...
