该方法的推导思路是：假设在某一控制储量条件下，联立求解气藏物质平衡方程式和气井二项式采气方程，计算气井采气曲线并将其与实际的采气曲线相匹配，最后确定储量、产能参数。该方法不需要较长的多次关井复压资料，在气藏受水驱影响较小时，还可计算一口探井或气藏试采早期所反映出的气井控制储量，在气藏生产中得到应用，计算结果较为可靠

It"s considered that the algae blooms control function in the algae"s growth dynamics model is influenced mostly by the water temperature, sun illumination, water flow speed and the concentration of the nutriment in water. A function including the four elements was built. By using cell mapping algorithm and contacting with the practical water condition of the Wujiang river and the Hanjiang river we analyzed and computed the algae blooms in the two areas and found the result was very near to the practical result. And we found that the ascend of water temperature and the descend of the water flow speed will contribute to the growth of algae and the nutriment is the substance basis of the algae blooms but not the only element. It must be under the condition of condign water temperature, enough sun illumination, slow water flow and abundant nutriment that algae blooms may break out unexpectedly.

本文认为藻类生长营养动力学模型中的水华爆发控制函数主要受水温、光照强度、水流速和营养盐浓度的影响，构建了包含水温、光照强度、水流速和营养盐浓度的水华爆发控制函数，通过对乌江、汉江的水华爆发进行胞映射分析，得到的计算结果与实际监测非常吻合，并认为水温升高和水流速下降将有利于藻类生长，营养盐是水华爆发的物质基础，但不是唯一因素，必须在适宜的水温、光照、缓慢的水流和充足的营养盐条件下，藻类才可能出现突发式的"疯长"，即水华爆发。

Influenced by tectonic movement, there were no sediments in the area from Oligocene to Miocene. Appearance of marlite in the Pliocene, especially in Yaqueling region, proved localized depositing environment forming, for which there had only few amount of terrigenous matters to supply. Sedimentary facies association of alluvial fan, fan delta and inland lake appeared at the early and middle stage of lower Pleistocene, and association of fan delta and inland lake appeared at the later stage of lower Pleistocene and the early stage of middle Pleistocene. Net-veined laterite appeared at the top of lacustrine deposit, which reflected pedogenesis taking place after the end of deposition. Such evolution history proves that there had no lager river system traversing this area before the early stage of middle Pleistocene.

对于江汉盆地西缘宜昌地区来说，其沉积及古地理演化表现为：早白垩世为受天阳坪断裂控制的内陆湖泊沉积环境，沉积中心在天阳坪断裂的北侧，此时几乎不存在来自黄陵地区的水系；晚白垩世同样为受断裂控制的内陆湖盆环境，但湖盆面积扩大、断裂活动减弱，且后期出现成化湖相沉积；第三纪早期盆地由断陷盆地转变为坳陷盆地，同时石膏的出现代表了局限咸化湖盆的存在；渐新世—中新世，受构造影响，缺失该时期的沉积；上新世时在鸦鹊岭一带出现的泥灰岩沉积反映了陆源物质供应不足的局限沉积环境的存在；早更新世早中期为冲积扇—扇三角洲—内陆湖泊沉积，早更新世晚期—中更新世早期为扇三角洲—湖相沉积，后期出现沉积结束以后的网纹红土化作用。

The results revealed that the condensable oAMCs with relatively higher molecular-weight possess greater sticking capability or potential, while those with relatively lower molecular-weight generally have greater adsorption rate at the initial exposure stage.

研究结果显示较高分子量之凝结性oAMCs具有较大之吸附能力；而较低分子量之凝结性oAMCs则在曝露初期具有较高之吸附速率，故在短曝露时间内，其吸附沈积量将大於较高分子量之凝结性oAMCs，因此在微污染的控制上，较低分子量之凝结性有机物质，将成为短时间曝露时主要污染控制对象。

On the other hand, these activities control the amout and quality of freshwater, for example, water used for agricultrue and industry increase, build up reservoir and unloading directly change the balance of the ecological eviromental composition such as salinity, sand, nutrious and microelement in soil, so that control the change of heteroptera Kitog.

人类活动一方面通过建设虾池、大坝及油井平台等活动直接占用了碱蓬生长的土地，另一方面它又通过控制上游淡水的水量与水质，如农业与工业用水的增加、建水库、直接排污等活动改变着区域土壤的盐度、泥沙成分、营养物质、微量元素等生境组分的平衡，进而控制碱蓬的消长。
