Then through series experiment of coupling beams only add diagonal bars on the basis of traditional reinforcement with Zhanlin, we can conclude this plan for steel bar can satisfied the ductility demand of short-span coupling beams in tube body structure of Chongqing area. Through the computer simulation we can know: Procedures outputs coupling beams'ductility demand mainly in 1.5 to2.0 (maximum value 2.2), comparing the simulation of 8 or 9 degree , we can see the response of the whole structure and yielding degree are much small.

计算机分析程序输出的连梁的转角延性大多在1.5到2.0之间(最大值2.2)，对比以往本学科点对8度和9度等高烈度区的同类型结构的地震作用模拟分析可以看出，6度区大震作用下不管是结构的整体反应还是各杆件的屈服情况都比高9度和8度区小很多。

结果表明，在热状况下，自然裸露区域桃园的空气温度日较差、日极端最高温度和20 cm高度处的空气平均温度均高于黑麦草套种区，空气湿度则黑麦草套种区明显大于自然裸露区。

Second, wetland landscape pattern dynamic change of Kenli County Take TM as the information source, according to studies the region wetland ecosystem present situation characteristic, wetland is divided into 10 kinds: irrigation paddy field, pit pond water surface, cultivation water surface, artificial ditch, reservoir water surface, salt field, rivers water surface, reed, shallow seas and tidelands, beach. The wetland landscape area is remarkable dropt from 1987 to 2004.In 1987 the wetland area occupied 14.10% of Kenli county, but only was 12.33% in 2004, it reduced 6155.12 hm2 in 17 years and average reduced 362.07 hm2 every year, the reduction scope of shallow seas and tidelands wetland is biggest 3894.78 hm2. The shallow seas and tidelands and reed are frequent transformation with other type.

2查清了研究区湿地景观格局动态变化规律以TM影像为信息源，根据研究区域湿地生态系统现状特征，把垦利县湿地分为10类；湿地景观面积在研究时段内呈显著下降趋势，1987年湿地面积占整个研究区总面积的14.10%，但到2004年只占12.33%，17年共减少6155.12 hm2，平均每年减少362.07 hm2，其中滩涂湿地面积减少幅度最大3894.78 hm2；从各湿地类型之间的转换来看，各种湿地景观之间、湿地和非湿地之间相互转化和逆转并存，滩涂和苇地与其他地类转换频繁；研究区湿地景观斑块数量增多，景观多样性指数1987年为1.7643，2004年下降到1.7105，均匀度指数由1987年的0.6873上升到2004年的0.6923。
