小钦岛土壤理化性质及其影响因子

目的：观察外伤一方加减治疗手足外伤的临床疗效。方法：将手足外伤患者80例随机分为2组，每组各40例，对照组采用西医常规治疗，治疗组在对照组治疗基础上加本院自制的外伤一方治疗。比较2组患者的综合疗效、VAS评分及满意率。结果：总有效率治疗组为100.0%，对照组为85.0%，组间比较，差异有统计学意义（P＜0.05）；2组疼痛VAS评分及患者满意率比较，差异均有统计学意义（P＜0.05）。结论：外伤一方加减治疗手足外伤有较好的临床疗效，能明显降低患者疼痛程度，提高患者治疗满意度。

Soil physicochemical properties and influencing factors on Xiaoqin Island

The main physical and chemical indicators of soil were measured in field investigation combineo with the belt transect and sample methods. Pearson correlation analysis, one-way ANOVA analysis and least significant difference (LSD) multiple comparison based on SPSS 24.0 were used to study the statistical characteristics of soil physical measured and chemical properties and influencing factors on Xiaoqin Island. The average soil gravel ratio and water content are 20.04% and 7.35%, respectively. The average values of ammonium nitrogen, available potassium, available phosphorus and organic matter are 23.67, 212.77, 16.15mg/kg and 28.34 g/kg, respectively, which is cdassified as the fifth, first, third and third grade, respectively. However, most of soil belongs to the third grade. Organic matter correlated positively in high significants with water content, ammonium nitrogen and available phosphorus. The physical and chemical properties of soil are mainly affected by vegetation and aspect. This profound study on one of Miaodao Islands is aimed to provide knowlege for the ecological protection and development of the island.
