On the basis of regional natural and cultural resources,Yunnan Province has created diversified agricultural operating types and colorful farming culture. Thus,it has significant comparative advantage in developing the landscape agriculture,but it should avoid homogeneous competition in construction methods. The landscape agriculture of Yunnan Province should set foot on special features of rural landscape,stick to its " local characteristics",raise core competitiveness of characteristic landscape,and take the ecological and characteristic development road.展开更多
目的：判别高原地区多脏器功能障碍综合征（multiple organ dysfunction syndrome at high altitude，H—MODS）各项诊断指标参数界值与平原地区的差异；验证新的评分诊断标准的准确性、可操作性。方法：按统一标准将总数为462例MODS患...目的：判别高原地区多脏器功能障碍综合征（multiple organ dysfunction syndrome at high altitude，H—MODS）各项诊断指标参数界值与平原地区的差异；验证新的评分诊断标准的准确性、可操作性。方法：按统一标准将总数为462例MODS患者根据海拔高度分为平原对照组（CG，n=113）、中度高原组（MHG，1517m，n=314）、高原组（HG，2808—3400m，n=35）。分别用平原地区MODS评分诊断标准（庐山会议标准和Marshall诊断标准）以及兰州修订的H—MODS评分标准，绘制ROC曲线（receiver operating characteristic curve），计算约登指数和最佳界值，验证3个标准在不同海拔高度预测MODS结局的准确性。结果：多脏器评分提示兰州标准随海拔梯度升高有进一步提高预测准确性的效果，P=0．034。分层分析还表明，肺、脑、心、肾等单项指标的ROC预测值也以兰州标准的适用度最高（P〈0．05）。结论：通用的MODS诊断标准中某些参数界值不适合中度高原以上地区；海拔高度大于1500m以上地区可能是区分平原和高原MODS诊断标准的一个有意义的分界线，值得进一步实践观察。展开更多
