- 摘要:
- 为了解我国北方农牧交错带气候对植被的影响规律，以宁夏盐池县为对象，采用样方调查法进行植被调查，并收集研究区降水、气温等气象资料。通过统计学方法对调查资料进行处理，并结合多年的气象数据分析了宁夏盐池气候变化对各种植被参数的影响。结果表明：在大时间尺度上，气温与植被生长呈负相关；在短期内，植被生长与气温关系不很明显；降水与盐池地区植被生长呈现明显的正相关，是植被生长的主要限制因子；降水的变化对植被的影响存在滞后效应，主要体现在植被盖度、植被高度和生物量上。
- Abstract:
- In order to understand northern agriculture and animal husbandry of our country interlocks and takes the law of climate impact on vegetation, this literary grace uses one kind of square investigation methods to carry on the vegetation investigation in a kind of ground of fixing already laid, precipitation, temperature, etc.meteorological materials of studying area are collected.Engage in the survey materials to deal with foreign countries through the statistics method, combine the impact on various vegetation parameters of climatic change of salt pond of Ningxia of meteorological data analysis for many years, The result shows:On yardstick in great time, the temperature and vegetation grow and present and is defeated by relevantly.In a short time, it is not very obvious that the vegetation grows with the temperature relation; The precipitation and vegetation of salt pond district grow and present obvious positive correlation, it is a main restriction factor of growth of vegetation; The lagging effect exists in the impact on vegetation of change of precipitation, mainly reflect it on the amount of degree, vegetation height and living beings covered of the vegetation.
