Abstract:

To understand current situation of farmland resource allocation and the influence of market economy on the slope of Yunnan planned tobacco area, the distribution and difference of slope types in core, high quality and suitable area were analyzed, based on the latest results of flue-cured tobacco planting zoning data and slope grid data. On this basis, combined with the data of rural per capita disposable income of each city, the impact of market economy on the slope of tobacco planting area was analyzed. The results showed that the planned area of flue-cured tobacco accounted for 47.9% of the total area of class Ⅰ and Ⅱ, and accounted for merely 18.7% of the total area of class I to III which was suitable for planting flue-cured tobacco in the whole province. However, 40.0% of the latest planned tobacco fields were in class III farming areas, and 26.3% in class IV and V areas. The percentage of class III to V flue-cured tobacco planning area in each prefecture and city was positively proportional to the per capita disposable income in rural areas, which indicated that the higher the disposable income, the more obvious the tobacco planting area developing to cultivated land with large slope. In general, under the effect of market economy, the development of flue-cured tobacco industry in Yunnan is at disadvantage in the allocation of cultivated land resources.
