基于土地適宜性的耕地規(guī)劃CA模擬及驗(yàn)證
[Abstract]:In order to explore scientific and reasonable methods of cultivated land planning, taking Lankao County, Henan Province as an example, this paper analyzes the suitability of farmland planning from three aspects: suitability, restriction and competition, and uses CA (cellular automata) simulation system. To simulate the planning of cultivated land under the control of indicators in Lankao County in 2020. The results showed that the cultivated land area in Lankao County was 76 411.32 hm~2, in 2020. The cultivated land area was reduced by 226.44 hm~2, to villages due to urban development, and the area of other land such as inland beach and orchard was converted to cultivated land area of 8 227.13 hm~2.. Based on the comparison of cultivated land suitability evaluation results, it is found that the cultivated land simulated in quality is higher than that in current land use planning, and the spatial distribution avoids the influence of urban development, ecological protection and other factors, and has stability. This study provides an important method reference for managers to formulate cultivated land planning.
