On the presentation of Mn-P fixation, this paper reviews the latest advances in recent 10 years and concentrates on the mechanism of phosphorus fixation in acid soils. In addition, it brakes through the classical inorganic P fractionation in to Fe-P, Al-P, O-P and Ca-Pin the traditional P classification and considers Mn-P as one of the main phosphorus fixation modes in latosols, cultivated from the parent basalt material. Furthermore, fixation of P by Fe, Al, Mn is compared, and differentiation from chemical availability and bioavailability of P discussed. Based on the above, this paper presents some alienable measures for enhancing P utilization efficiency and postulates pivotal future research directions in the field of P fixation.

本文以Mn-P的提出为出发点，论述了近10年来对酸性土壤固磷机理研究的新进展，突破了常规P素形态分级研究中分为Fe-P，Al-P，O-P和Ca-P等无机磷测定的经典分级，认为玄武岩母质砖红壤中的Mn-P是P素固定的主要形式之一，进而比较了Fe、Al、Mn对P固定作用，并从P的化学有效性与生物有效性差异等方面进行了比较全面的论述，提出了减少P素固定提高磷肥利用率的措施及今后的重点研究方向。

Thirdly, Lower-grade plants such as lichen, bryozoan etc. begin to grow. Along with the accumulation of living beings is going more and more, the amount of organic matter in the parent material forming soil is going more and more, Then higher-grade plants gradually replace lower-grade plants, and through strong and extensive root system, the dispersive and soluble nutrition can be concentrated. After the death of organisms, and through decomposition of microbes, one part of the remains of the organisms becomes nutrients for plants, and another part of the remains turns into humus.

第三步，地衣、苔藓类低等植物开始生长，随着生物的积累作用越来越大，成土母质中的有机物数量不断增加，最后高等植物逐渐取代了低等植物，通过强大的根系把分散的可溶性养分集中起来，等到这些生物死亡之后，它们的残体经过微生物的分解作用，一部分成为后来植物所需的养分，另一部分变成了腐殖质。

Results are as following:The causes of grassland desertification of Hulunbeir are the outcome of interaction of nature and the human beings. Among these reasons, the loose soil texture, which was formed in the fluviolacustrine sediment during Quaternary, establish the physical ground, and the drought and wind is the natural force of grassland desertification. And then over-cutting forest, over-grazing grassland, imbalance of resource utilization and estrepement reduce the coverage of vegetation, therefore provide necessary conditions for the grassland desertification.

其中，形成于第四纪河湖相沉积沙的疏松土壤母质，为日后土壤风蚀奠定了深厚的物质基础；干旱多风的气候条件构成了草地风蚀沙化的自然营运力；而人为过度砍伐沙地林木资源、沙质草地长期超载放牧、资源利用不平衡以及乱垦、滥挖等不合理经济行为，又降低了沙化草地植被覆盖度，为草地风蚀沙化提供了必要条件。

Luliang Basin is of a series of good conditions of forming commercial biogenic methane gas reservoirs,such as the excellent type of kerogen,high organic matter abundance,low-salinity hydrochemical property,suit a ble geotherm,immature hydrocarbon source rocks and fair structural-lithological traps,etc.

During the Early Carboniferous, glacio-eustasy and the palaeogeographic environment of Qiangui intra-platform basin played crucial roles in controlling the geobiological processes, the formation and distribution of basinal facies hydrocarbon source rocks.

早石炭亚纪冰川性海平面变化及黔桂盆地独特的古地理位置控制着盆地中的地球生物学过程，决定了生烃母质生物的生产力和有机质的保存条件，进而影响了盆地相烃源岩的形成与分布。

The organic styles are mainly composed of sapropel humus.

但含煤段油页岩沉积时期高温、湿润的古气候条件下的喜湿植物面貌，使油页岩母质类型具有较多的富氢组分，这是造成两套油页岩品质差异的主要原因。

2The natural gas of Ordovician is typical petroliferous gas which came from the same source rock. It is a composite of gas that was generated from the sapropelic parent material of different maturity. Its maturity varied from mature degree to high-over mature degree which decreased from east to west and from southeast to northwest.

2塔河油田奥陶系天然气为典型的油型气，具有相同的来源，为腐泥型母质不同成熟阶段生成气的复合，成熟度范围覆盖从成熟阶段到过成熟阶段，成熟度从东往西、从东南向西北逐渐降低，天然气的产生具有多阶连续的特征。

That is, U-enriched muscovite peraluminous granites are the uranium source for metallogenesis, and the uranium is mainly devided from the parent granite rocks weathered and denudated, not from the hydrothermal solution derived from the parent granite rocks.

即铀含量较高的晚期二云母过铝质花岗岩是铀成矿作用的铀源，而且，铀源主要来源于被风化并剥蚀掉的那部分母岩，而不是来源于热液流体对现存母岩的交代。
