Theoretical calculation shows the anomaly of reservoir tidal gravity is measured at μGal level, while the measured data shows the observation error of such tidal gravity at 10-μGal level. This indicates that the data noise may well disguise real anomalies, and therefore that the lack of measured anomaly data does not necessarily equate to the lack of oil and gas reservoir underneath. The actual observed tidal gravity anomaly can reach tens of μGal. Though it is more than three times the observation error, we can not attribute it to the reservoir-induced tidal gravity anomaly.
理论计算表明,油藏潮汐重力异常在微伽量级,而实际资料表明潮汐重力的观测误差为10 μGal量级,油藏潮汐重力异常可能会被噪声淹没,所以没有观测到潮汐重力异常不等于地下没有油气;实际观测的潮汐重力异常可达数十μGal,即使超过观测误差的3倍,也不能将它直接归因于油藏产生的潮汐重力异常。

This doctoral dissertation is composed of several parts: At beginning, the frontal structure, the effects of diabatic heating and orography, the dynamics of frontal circulation and the mesoscale systems associated with front are reviewed. Several problems based on the review are brought forward. First, at present, the semigeostrophic frontogenesis theory is the most appropriate basic framework for the general explanation of the frontogenetic process. However, the comparison between semigeostrophic theory and the observation have revealed some inconsistencies. The newly observational facts increase the inconsistencies.

The following conclusions have been made in this paper.(1) Based on CO_2 flux data of eddy covariance, variation characteristics of gross primary productivity in four flux observation stations were studied, which are an alpine meadow, an alpine shrub meadow, a swamp alpine meadow and a steppe alpine meadow at Dongxiong. The results show that photosynthetic capacity of the alpine meadow is the highest, and the annual total GPP is 652.2g C/m~2. Daily-differencing approach is used to analyze the random error of CO_2 fluxes measurements. The results show that the distribution of random error follows more closely follows a double-exponential, rather than a normal distribution, capturing the high peak and thick tail, and the random error varies with environment variables, which violates the assumptions for the ordinary least squares fitting with normality and homoscedasticity, consequently, we introduce maximum likelihood method for parameter optimization.
本文主要在以下几个方面开展工作并获得了一些认知和结论:(1)通过分析样带区域内高寒草甸、高寒灌丛、沼泽化湿地和草原化高寒草甸四个通量观测站点草地生态系统总初级生产力变化特征,研究结果表明HBBT矮嵩草草甸生态系统植被光合作用能力较强,年GPP总量为652.2 gC/m~2,明显高于其他三种生态系统;通过利用"单塔日变化法"获得四站点通量观测数据随机误差,结果表明通量观测随机误差概率分布呈现尖峰厚尾的特征,与正态分布相比,更服从双边指数分布,进一步分析表明通量观测随机误差随环境变量(风速、温度和光合有效辐射)的变化而变化,这违背了普通最小二乘法进行生态过程模型参数优化正态分布且误差同质的假设,因此本研究中引入最大似然法进行生态过程模型参数优化。

According to the observation experiment at the Jiufeng station where there is smaller environment noise, the conclusions are drawn as follows.In the normal atmosphere, the observed value is about 500×10-5ms-2, which is greater than theoretical value about 30×10-5ms-2, and if in the low vacuum, the observational error about 2.3×10-5ms-2 is generated. The vacuum maintaining system in falling room can not work normally, which will yield 0.1~4.1×10-5ms-2 error to the gravimetric observation. In the case of that the measurement is in the stable geological conditions and the smaller environment noise, the action of vibration isolating spring is not obvious, but it yields greater effects on measurement accuracy.

The CO2 uptake rate of plants is affected by the plant species and environmental conditions such as photosynthetically active radiation, temperature, water and nutrient contents. PAR is the most immediate environmental control on photosynthesis while air temperature affects both photorespiration and dark respiration. In the natural condition, PAR and temperature play an important role in net CO2 uptake. The effects of PAR and air temperature on the CO2 uptake of Pterocarpus macrocarpus grown in a natural habitat were studied in the present work. Due to many uncontrollable factors, a simple rectangular hyperbola could not represent the measured data. The data were divided into groups of 2℃ intervals; CO2 uptake in each group may then be related to PAR by a rectangular hyperbola function. Using the obtained functions, the effect of PAR was removed from the original data.
用涡度相关法对亚热带红壤丘陵区人工针叶林的二氧化碳、水、热通量进行了观测,重点分析了23m、39m两层高度的观测结果,同时把观测期分为春季和冬季两个不同时间段作了对比:结果表明,不管冬季还是春季,39m高度所测的总通量值和夜间通量值都要小于23m的观测值,这种通量差别表明:23m高度的观测结果更接近当地生态系统与大气之间的通量交换值,在此种生态类型条件下用涡度相关法测碳通量时,在23m、39m两层高度之间仍然存在大气平流现象;该试验区植被在冬季仍然可以进行光合作用,而且光合作用所吸收的CO2大于呼吸作用所排放的CO2,因此该种生态系统在冬季仍表现为碳汇;春季的碳通量值为冬季的2倍以上。

Observed value:观测值
也即它是由单次观测所得,还是由多次观测所得. 若是单次,则观测值(observed value)就是测量结果. 若是对同一量的多次观测,则其算术平均值才是测量结果;在很多精密测量的情况下,测量结果是根据重复观测确定的.
