- Abstract:
-
In order to improve the coordinated development of social economy and ecological environment protection, take into account the relationship between residents' lives, food production and ecological protection, taking the middle reaches of the Heihe River as an example, we used geographic analysis methods to explore the temporal and spatial evolution and spatial conflict distribution characteristics of the land for production-living-ecological. It was found that during the period from 1975 to 2016, the ecological production land and ecological land in the middle reaches of the Heihe River were transformed into production ecological land and living production land. The ecological production land and ecological land reduced by 58 324 hm2 and 33 923 hm2, respectively. The area of living production land and production ecological land increased by 12 581 hm2 and 79 667 hm2, respectively; the number of patches of production-life-ecological land in the middle reaches of the Heihe River increased from 3 505 in 1975 to 6 019 in 2016. This result indicated that the landscape pattern was developing in a fragmented direction. The result of the change in the landscape pattern index at the class level showed that the spatial structure complexity of ecological land, production ecological land and ecological production land were weakened; the agricultural and pastoral transition zone and the land-water transition zone had a strong level of spatial conflict, of which conflict between ecological production land and ecological land was the most significant; The spatial conflicts of tertiary land use in the middle reaches of Heihe were on the decline.
