Grassland Vitality Monitoring Based on Remote Sensing in Manas River Basin in Northern Slope of Tianshan Mountain
[Objective] We analyzed the grassland vitality by using the domestic GF-1 remote sensing imagery data in order to provide the scientific basis for preserving the sustainable development of animal husbandry and maintaining the regional ecological balance.[Methods] The typical steppe area of Manasi River basin in Xinjing region was selected as the study area. Based the "3S" technology
GF-1 remote sensing images in 2013 and 2014 were collected and the field survey was conducted to monitor the growth of grassland.[Results] The growth of grassland in 2014 was poorer than that in 2013
and the area of grassland with poor growth was 209 074.7 hm2 in 2014 more than that in 2013
which accounts for 13.21% of the total area of grassland in the study area. Comparatively
the largest area with poorer grass growth in 2014 was temperate desert grassland
which was about 109 224.6 hm2
accounted for 36.8% of the temperate desert grassland and 6.9% of the total grassland in the study area.[Conclusion] The monitoring accuracy of grassland vitality in the study area is high
which is more than 88.6%
indicating that GF-1 remote sensing imagery data is useful in the monitoring of grassland growth.
