中文摘要:
      本文以盘州市为例,对影像采用目视解译、地学统计分析及实地调研等方法获取2017年和2019年的刺梨种植空间分布特征,引入RS和GIS技术手段详细研究了2017年和2019年的刺梨种植空间分布格局时空变化特征与地形因子、土壤养分含量之间的相关性。研究结果表明:(1)受海拔、地貌类型和城市分布的影响,通过2017年和2019年的刺梨种植空间分布格局两期监测数据,直观地看出盘州市刺梨种植主要在除中部以外区域的空间分布特征;(2)盘州市刺梨种植空间分布面积占比情况和种植面积增加区域的占比情况均与全市的坡度分类面积占比规律一致,其坡度类型占比最大为缓陡坡(坡度为15o~25o),2017年和2019年刺梨种植空间分布主要在缓陡坡类型,其面积所占比值分别约为30.88%和31.01%,2019年相比较2017年在各个坡度等级种植面积均有增加,在缓陡坡类型刺梨种植增长量占整个增长面积的百分比最大,约为35%,刺梨种植面积占比主要分布在地形起伏度为70~200m范围内;(3)盘州市的土壤PH平均值约为5.98,为适宜种植刺梨的微酸性土壤,有机质、全氮、速效钾等含量主要为丰富和极丰富范围值,有效磷的含量较低,在刺梨种植过程中,应适量追加相应磷肥。(4)将取样土壤中有机质、全氮、速效钾和有效磷等元素含量预测图与刺梨监测矢量数据进行空间叠加分析,对其进行统计分析,结果表明土壤中各元素含量的丰富程度符合刺梨种植空间分布格局及变化情况,但有效磷的含量偏低,需要在种植过程中人工追加磷肥。
英文摘要:
      Taking Panzhou City as an example, this article uses visual interpretation, geo-statistical analysis and field investigation to obtain the spatial distribution characteristics of Rosa roxburghii Tratt planting in 2017 and 2019, and introduces RS and GIS technology to study the correlation between spatial and temporal characteristics of the spatial distribution pattern of Rosa roxburghii Tratt planting in 2017 and 2019, besides of topographical factors and soil nutrient content. The research results show that: (1) Affected by altitude, landform type, and urban distribution, through the two-phase monitoring data of the spatial distribution pattern of Rosa roxburghii Tratt planting in 2017 and 2019, it can be intuitively seen that Rosa roxburghii Tratt planting in Panzhou City is mainly in the central part The spatial distribution characteristics of other regions; (2) The proportion of spatial distribution of Rosa roxburghii Tratt planting area in Panzhou City and the proportion of planting area increase area are consistent with the proportion of the city"s slope classification area, and its slope type accounts for the largest proportion. Gentle and steep slopes (slopes of 15o~25o). The spatial distribution of Rosa roxburghii Tratt planting in 2017 and 2019 is mainly on gentle and steep slopes, and their area ratios are about 30.88% and 31.01%, respectively. Compared with 2017 in various grades The planting area has increased, and the growth of Rosa roxburghii Tratt planting in the gentle and steep slope type accounts for the largest percentage of the total growth area, about 35%. The planting area of ??Rosa roxburghii Tratt is mainly distributed in the range of 70~200m of terrain undulation; (3) The average soil pH in Panzhou City is about 5.98, which is a slightly acidic soil suitable for planting Rosa roxburghii Tratt. The content of organic matter, total nitrogen, and available potassium are mainly rich and extremely rich range values. The content of available phosphorus is low. During the planting process, appropriate amount of phosphate fertilizer should be added. (4) Analyze the spatial superposition analysis of the organic matter, total nitrogen, available potassium and available phosphorus content prediction map of the sampled soil with the Rosa roxburghii Tratt monitoring vector data, and perform statistical analysis on it. The results show that the richness of each element content in the soil is consistent with The spatial distribution pattern and changes of thorn pear planting, but the content of available phosphorus is low, it is necessary to artificially add phosphate fertilizer during the planting process.
