The factors affecting postfrac productivity are discussed in the paper. The grey associability ordering indicated that the postfrac productivity was lowly correlated with the permeability interpreted by the original log data and mainly influenced by porosity, then effective thickness, and then shale content and formation pressure. In light of the genetic neural network method, the productivity of gas well was predicted by use of the log data through programing and model training. The error detecting result proved that the model was reliable and a good application effectiveness was obtained.

文章对压后影响产能的因素进行了讨论，灰关联度排序表明，压后产能与原始测井解释的渗透率关联性小，而主要影响因素依次是孔隙度、有效厚度、泥质含量和地层压力；引用遗传神经网络法，编制预测程序，利用测井资料通过模型训练，对气井的产能进行预测，误差检验验证了模型的可靠性，取得了良好的应用效果。

Results showed that the CO2 absorb ability in the eight Crop systems net productivity process was 4 032 366ta^(-1); the amount of CO2 outlet in the soil was 3981753ta^(-1), less than the CO2 adsorb ability, so that the whole crop system was a weaker carbon sink process in the atmosphere. The continue planting species such as Rice, sugarcane, cassava, and melon crop or high haulm crops have the characteristics of annually crop net productivity CO2 absorb ability bigger than soil CO2 outlet and this systems had bigger carbon sink function ability; the short haulm crop systems of peanut, soybean, flowers, and vegetable annually crops net productivity CO2 absorb ability less than soil CO2 out let, but also carbon sink source. The CO2 absorb ability of fruits and economic parts above ground bigger than that which growth under ground. Except of the CO2 absorb ability less than the soil CO2 outlet in the peanut during growth in procreate period, the other seven crops CO2 absorb ability were bigger than that soil CO2 outlet during procreate period. Most of crops during growth in procreate period had carbon sink function ability, and only in barren period showed the carbon source function phenomenon.

结果表明：2005年广州市8种农作物系统作物净生产力吸收CO2 4032366ta^(-1)，其土壤CO2排放3981753ta^(-1)，吸收大于排放，对大气CO2而言，整个农作物系统是一个弱的碳汇；水稻、甘蔗、木薯和果用瓜4种连作或高杆作物系统每年作物净生产力吸收CO2量大于土壤CO2的排放量，系统具有较大的碳汇功能，花生、大豆、花卉和蔬菜4种矮杆作物系统每年作物净生产力吸收CO2量小于土壤CO2的排放量，系统起着碳源作用；果实或经济产量生长在地上部分的作物其单位面积吸收CO2能力比果实生长在地下的作物大；除花生在生育期间生物量吸收CO2量少于同期土壤排放以外，其余7种作物在生育期间生物量吸收CO2的量大于同期土壤排放，大多数农作物在生育期间具有碳汇功能，在撂荒期才体现碳源作用。
