【摘要】：為探討土壤特性和地形特征這2個(gè)最為核心的耕地資源限制因子影響下的可用于耕地的土地資源,在前人研究的基礎(chǔ)上,綜合考慮土壤類型及其性質(zhì)和地形影響,以ArcGIS分析工具為平臺(tái),構(gòu)建耕地資源識(shí)別模型,對(duì)錦西灌區(qū)內(nèi)可用于耕地的土地進(jìn)行識(shí)別分析。結(jié)果表明:在錦西灌區(qū)1 200.59km~2的土地中,568.33km~2適宜耕地,較適宜耕地的面積為5.92km~2,改良后適宜的面積為564.15km~2,僅62.19km~2不適宜耕地,不適宜耕地部分包括受土壤因素限制的34.19km~2和受地形影響的32.00km~2,綜合考慮兩方面的因素所得面積為62.19km~2。與傳統(tǒng)的識(shí)別方法比較,本研究所構(gòu)模型對(duì)最核心的限制因素進(jìn)行綜合考慮,可更全面、更客觀、更精準(zhǔn)的識(shí)別可用于耕地的土地資源。
[Abstract]:In order to explore the land resources that can be used in cultivated land under the influence of soil characteristics and topographic characteristics, the soil types, their properties and topographic effects are considered comprehensively on the basis of previous studies. Based on the ArcGIS analysis tool, the identification model of cultivated land resources was constructed to identify the arable land that could be used in Jinxi irrigation area. The results showed that in the land of 1 200.59km2 in Jinxi Irrigation District, 568.33km2 was suitable for cultivated land. The suitable area of cultivated land was 5.92 km2, and the suitable area after improvement was 564.15 km2, only 62.19 kmm2 was not suitable for cultivated land. The unsuitable cultivated land consists of 34.19kmm2 restricted by soil factors and 32.00kmm2 affected by topography, and the area obtained by comprehensive consideration of the two factors is 62.19kmm2.Compared with the traditional identification methods, the most core limiting factors are synthetically considered by the model. Can be more comprehensive, more objective, more accurate identification of arable land resources.
