Taking household\'s land use preference as classification rule, household agent types were divided though classification tree. Different choosing process of current production strategies and theirs probabilities after expiration of GFGP chosen by various types of household agents\' were put forward by experience-weighted attraction model based on bounded -rational approach. Finally, forecasting the results of households\' recultivation behaviour after the expiration of GFGP by scenario analysis method. The results show that relative policies are useful to rectify deviation of households\' bounded-rational behaviours and reinforce outcomes of GFGP.

以农户家庭户主的土地利用选择偏好作为分类依据，采用分类树方法对农户智能体类型进行划分；基于有限理性决策理论，引用经历—权重吸引模型，对农户智能体的目前生产策略决策过程和退耕还林政策期满后农户对不同生产策略的选择概率进行了分析；最后，在ERDAS环境下对退耕还林政策期满后农户的复垦行为进行了情景分析，认为政府制定并实施的相关政策措施对于纠正农户的有限理性行为偏差，维持和巩固退耕还林政策成果具有重要作用。

晚侏罗世以后，太平洋板块对研究区的影响占主导地位，随着俯冲角度的变陡和俯冲带向洋的后撤，全区由挤压为主转变为以拉张为主的应力环境，由于基底属性有所差异，在扬子地块区域形成以拗陷盆地为主的伸展裂陷盆地，在华夏地块区域形成了火山断陷盆地，而在两大地块边界附近，则形成了一系列半地堑式的红色断陷盆地。

Modeling and stability analysis problem of linear switched system are emphasized in this part and main results include:(1) Through investigation in the projection of 〓 on x, where x denotes continuous state vector, a series of sufficient conditions for stability, asymptotic stability and unstability of linear switched system's equilibrium in the sense of Lyapunov are achieved. And also, a sufficient and necessary condition for state bounded stability of linear switched system is received.(2) For a class of periodical linear switched system whose switching sets are a group of ordinal lines starting from the original point, it's proved that state bounded stability can be defined by the running characteristic in a single period (3) Based on linear switched system, the concept of linear switched system network is put forward. Linear switched system network is a complex network interconnected by many linear switched systems.

这部分着重研究线性切换系统的建模与稳定性分析问题，主要成果包括：（1）通过考察〓在x上的投影，得到线性切换系统的平衡点在Lyapunov意义下稳定、渐近稳定及不稳定的一系列充分条件，并得到了线性切换系统状态有界稳定的一个充要条件；（2）证明了对于一类切换集为从原点出发的一组射线的周期线性切换系统，其状态有界稳定可根据一个周期内的系统运行特性来判定；（3）在线性切换系统的基础上提出了线性切换系统网络的概念，线性切换系统网络是由多个线性切换系统交互作用而形成的复杂网络。

However, for the collision processes in He target, a large discrepacy between the CTMC results and experimental measurement is found. As is well known, the microcanonical distributions of bounded electrons in CTMC method is quite different from quantal distributions, we modified the initial microcanonical distribution by using eleven different ionization thresholds of electron bounded in target. With modification, we calculated the collisional process of O~(3+) with He, and the total cross sections of all processess are calculated as a function of the incident energies. The agreement with experiments is improved by the modified distributions.

但由于靶电子的微正则分布与量子分布有很大不同，在计算离子与He靶碰撞时发现结果与实验差距很大，我们基于使用多个系统总能量U值，对初始电子的微正则分布进行了优化，使其更接近于量子力学的径向空间分布，然后计算了O~(3+)与氦原子随入射离子能量变化的各种反应过程截面，发现优化极大地提高了计算精度，特别是我们的模型对于描述单电子、双电子丢失过程非常成功。

Compared with the single-bounded questionnaire format, the double-bounded questionnaire format could obtain more information about the respondents' willingness to pay, hence, it reduces the confidence interval range and improves the estimation accuracy of the greatest willingness to pay. At the pilot practice for three continuous years, the percent of banana windstorm insurance pilot size in the total banana planting area was less than 10% in Hainan. Combined with this research result, the author holds that Hainan finance should strength the subsidy to banana windstorm insurance on the basis of 30% subsidy in two continuous years of 2007 and 2008, and the subsidy percentage should try to achieve 40%. At the same time, the premium rate should not be too low, 18% is suitable.

与单边界问卷格式相比，双边界问卷格式能够获得被调查者支付意愿的更多信息，从而缩小了估计的置信区间，提高了最大支付意愿的估计精度；在连续3年的试点实践中，海南香蕉风灾保险试点规模占其香蕉种植面积不足10%，结合本研究结果，笔者认为海南省财政应在2007、2008连续两年30%的财政补贴基础上进一步加大对香蕉风灾保险业的补贴力度，力争补贴比例达到40%左右，同时费率也不宜过低，宜保持在18%左右。

Based on the field survey of 681 banana planters in Hainan province, the optimum questionnaire format of CVM, dichotomous choice format was adopted, using the single-bounded and double-bounded dichotomous contingent valuation technique to estimate the optimal size of financial subsidies to banana windstorm insurance accurately.

基于海南省681户蕉农的实地调查，采用CVM调查中最适宜的问卷形式－二分式问卷格式，运用单边界、双边界二分式条件价值评估方法，较精确地测度出香蕉风灾保险的最优财政补贴规模。
