摘要：The eco-environment in the agro-pastoral ecotone of Horqin sandy land is fragile and the land use is unreasonable. Based on the typical mother-son mountain villages in ecological environment, population and economy, and according to the interpretation data of remote sensing images and field survey data, the present situation and dynamic changes of land use in the village area were quantitatively analyzed from the micro perspective. The results show that the cultivated land area of Mother and Son Mountain Village village has fluctuated in the past 25 years, increasing from 836.53 hm² in 1990 to 1011.01 hm² in 2000 and decreasing to 651.23 hm² in 2015; the pasture area has decreased from 1437.15 hm² in 1990 to 675.8259 hm² in 2015; the grassland coverage has decreased, and the grassland with high coverage has decreased in 1990. The annual proportion of grassland area was 13.58%, which decreased to 0 in 2015; the forest coverage increased rapidly from 17.6% in 1990 to 53.1% in 2015; and the desertification land area decreased sharply from 13% in 1988 to 3%. In the past 25 years, the land use change index of Mt. Mozi is 9.35. The degree of human land change is increasing, and the relationship between human and land is becoming closer and closer. The degree of land use has changed from low level to high level. The main reasons are population factors, changes in livestock and the results of the adjustment of national policies. The farming-pastoral ecotone in Horqin Sandy Land includes Horqin Right Wing Middle Banner of Xingan League, Tongliao City and Chifeng City, each of which has a total land area of about 142,500 km² and a population of 6.167 million, of which the rural population is 493,480,000 ^[1]. Historically, the area was dominated by animal husbandry, with abundant aquatic plants and cattle and sheep everywhere. Due to the rapid growth of population and unreasonable land use over a long period of time, the ecological system of the area was degraded and the economic development was backward. Fourteen of the 16 banner counties belonged to poverty-stricken counties. Reasonable land use is the key to ensure the ecological security and economic development of the region. Relevant experts and scholars have carried out extensive research on this issue, but most of them are based on macro-level research, which can better show the large-scale pattern changes, but the quantitative research on micro-level is rarely reported. The research based on micro-perspective is more convenient to grasp the essence of the development of things and reveal the inherent law of the development of things^[2]. In the ecotone of agriculture and animal husbandry, there are significant regional differences in both natural and human aspects. Therefore, in order to fundamentally solve the ecological and economic problems in the region, the micro-quantitative research in different regions must be focued on. Based on the typical mother-son mountain villages in ecological environment, population and economy, the author conducted a field survey in August-September 2016. Combined with the statistical data of township government and village committee and remote sensing image data provided by relevant departments, the author analyzed the dynamic changes of land use in the past 25 years and made use of soil. The dynamic degree model of land use is used to measure the degree of comprehensive land use in order to provide scientific basis for the rationalization of land use and the sustainable development of agriculture and animal husbandry in this area.
