利用新疆环塔里木盆地地区的地理信息数据及气象资料,结合气象要素细网格推算模型和精细化农业气候区划软件的空间分析功能,对影响该区杏树种植分布的主导气候因子和该区杏树种植分布与气候的关系进行研究。结果表明:1)影响该区杏树种植分布的主导气候因子有:3月下旬和4月极端低温、极端温度出现的频率、≥10℃年积温、年极端最低气温、12月—次年3月日均温7℃以下天数;2)将该地区潜在种植分布区划分成4个等级:气候最适宜区、适宜区、次适宜区和不适宜区,并给出了各个气候适宜区的气候因子特征。揭示了新疆环塔里木盆地地区杏树种植的潜在分布及其气候适宜性,从气候适宜度的角度观察,该区杏树生产布局还有待进一步优化。 Based on the geographic information data and meteorological data of the Central and East Tarim Basin in Xinjiang and the spatial analysis function of fine grid meteorological elements and fine agro-climatic zoning software, the dominant climatic factors that affect the distribution of apricot planting in this area are analyzed. The relationship between tree planting distribution and climate is studied. The results showed as follows: 1) The dominant climatic factors affecting the distribution of almonds in this area are: extreme low temperature in late March and April, frequency of extreme temperature, accumulated temperature ≥10 ℃, annual extreme minimum temperature, December-next year 3 Month average daily temperature below 7 ℃; 2) Potential planting areas in this area are divided into four grades: the most suitable climate zone, the suitable zone, the sub-suitable zone and the unfit zone, and the climatic factors feature. Reveals the potential distribution of apricot planting and its climatic suitability in the Central Tarim Basin, and from the perspective of climate suitability, the production layout of almond trees in this area needs to be further optimized.

税收遵从成本作为税收成本的重要组成部分,是现代税收理论与实践研究的前沿课题之一。经过几十年的发展,国外对税收遵从成本的研究取得了丰富的成果,并达成了如下的共识:高额的税收遵从成本不仅降低了纳税人的遵从度,而且也直接导致税务部门的征管改革难以取得理想效果。税收遵从成本的研究在我国则起步较晚,以其为研究对象的著作较少。国内对税收遵从成本的研究更多的注重理论层面的探讨,尽管一些发达省市的学者对各自辖区范
