Spatial pattern and spatio-temporal change of territory space in Hengduan Mountains region in recent 25 years
Hengduan Mountains have a high ecological value and offer resources for a variety of ecological services.However;the sustainable development and management of territory space has been challenged by increased human activities in recent years.In this paper;we used the land use data of Hengduan Mountains in1990;2000;2010 and 2015 to analyze the quantity and structural changes and spatial pattern changes on various types of territory space at different elevations;and reveal the characteristics and influencing factors of recent changes in various territory space patterns.The results show that;the territory space in the Hengduan Mountains has relatively high altitudes and significant vertical differences.Within the ecological-production-living space schema;the ecological space dominates the Hengduan Mountains;while the production and living space are mainly distributed in the southeastern Yunnan plateau.During the last 25 years;the ecological-production-living space changes in the Hengduan Mountains have been gradually accelerated and the regional differences have become more prominent.The agricultural production space has continuously decreased;while the industrial and mining production space has increased rapidly in the last 15 years.The living space has steadily increased;and the ecological space has increased with fluctuations.The territory space pattern in the study region is greatly restricted by the natural factors such as altitude and slope.The implementation of China Western Development strategy and Grain to Green Project have favorably promoted the changes of territory space pattern in this region.At present;the territory space in the Hengduan Mountains still faces the problems of destruction of ecological environment by high-altitude industrial and mining exploitation;soil erosion on sloping cultivated land and natural disaster.In the future;the national spatial optimization development in the Hengduan Mountains needs to strictly control the production space of industrial and mining industries;ensure the ecological space;carry out the protection of basic farmland;implement the reforestation of sloping cultivated land gradually;and strive to strengthen the construction of disaster prevention and mitigation system in living space.
