Some innovative results are listed below:1、According to the lithologic characters,lithofacies,genetic classification and the geomorphy,the Quaternary system is divided into piedmont-gully\'s and plain\'s. The piedmont-gully\'s Quaternary sediment,which is about 3~20 meters in thick,is in the western hills of the study area.The plain\'s Quaternary sediment is widely distributed in the study area,which is about 30~60meters thick and become thicker from southwest to northeast.2、The Quaternary sediments of plain can be divided into five sedimentary cycles.The Late Pleistocene series Quantan group,at the bottom of the Quaternary System,is constituted by a fluvial facies-river and lake facies sedimentary cycle. The Late Pleistocene series Jiashan group,at the middle of the Quaternary sediment, is constituted by two fluvial facies-neritic facies-river and lake facies sedimentary cycles.The Holocene series Binhai group,at the upper of the Quaternary sediment, is divided into three parts,the under layer and middle layer are constituted by two littoral facies-river and lake facies sedimentary cycles,the upper layer is constituted by paludal facies,which was deposited at the lower-lying land like West Lake, Jiangcun-Gu dang,Xianghu lake,and coastal-estuary facies in other area.3、Folding and fault activities were weak in Quaternary and the tectonic activity had little influence on the Quaternary sedimentation.The ancient landforms,the evolvement of the river system and transgression were the main elements which controlled the Quaternary sedimentation in Hangzhou.The ancient landforms formed the basis of the Quaternary sedimentation.The evolvement of the river system and transgression individually or jointly controlled the Quaternary sedimentation of this area.4、The alternation of the climate was the main reason for the evolvement of the river systems and transgression,and it\'s also the reason why the Quaternary system of Hangzhou has the special sedimentary structure which is called soft interbed with hard layers.
通过研究取得了以下成果:1、根据岩性、岩相、成因类型和地貌特点,将本区第四系划分为山麓沟谷区沉积和平原区沉积:山麓沟谷区第四系主要分布于西部丘陵地区,厚度较薄且变幅大,一般厚3~20m;平原区第四系广布分区,由南西向北东逐渐增厚,一般厚30~60m.2、平原区第四系自下而上大体由五个完整或不完整的沉积旋回构成:底部上更新统全塘组,由河流相—河湖相的沉积旋回构成;中部上更新统嘉善组,由河流相—浅海相—河湖相两个沉积旋回构成;上部全新统滨海组,其下中两段由滨海海湾相—河湖相的两个沉积旋回构成,上段由西湖、蒋村—古荡、湘湖等低洼处沉积的湖沼相和其他地区沉积的滨海河口相构成。3、第四纪以来,研究区内褶皱、断裂活动微弱,构造运动对第四系沉积的影响不大,古地形、古水系的发育、变迁和海侵是杭州市第四系沉积的主要控制因素:古地形构成了第四系沉积的基底,水系与海侵在其后的不同阶段或分别或联合的主导了区内的第四系沉积。4、水系的发育、变迁和海侵的共同原因是天气变化,正是由于第四纪以来"冷热交替"的天气特点形成了杭州市第四系"软硬互层"的特殊沉积结构。

The CCFG is a kind of economical activity with positive externality, its final products offered -the ecological benefits belong to the pure public goods, the nature of the economical compensation is to internalize the externality of the CCFG, so an economical compensation mechanism should be established with the government playing a leading role. The compensation receivers should be not only peasant households but also the county-level authority that performs the project. Besides central government, the compensation payers should still include the provincial-level governments who implement the project, the provincial-level governments of those beneficiary areas of midstream and downstream of basin, international organizations, enterprises and individuals, etc. Multiple channels of raising funds for the program should be worked out and the practice method should be transformed. Thediversified compensation ways should be chosen. In reality, insufficient compensation is the normality, the cost compensation may have more maneuverability. The decision-maker should carry on proper adjustment to the compensation standard, taking into account the factors about the environment conditions, the social-economic conditions, the ecological function of vegetation, etc. and make out different compensation criterions for different areas and different levels. The author puts forward it should be kept the policy of financial subsidies to the farmers who reforest ecological forest for a long term, should prolong the compensation time frameworks to the farmers who reforest economical forest.
本文认为,退耕还林还草是一项具有正外部性的经济活动,其提供的最终产品—生态效益属典型公共产品,经济补偿的实质就是要实现这种外部性的内部化,故应构建以政府为主导的经济补偿机制;补偿对象除了退耕农户以外,还应包括实施退耕还林还草的县级政府;补偿主体除中央政府外,还需将退耕地区省级政府、流域中下游受益地区的省级政府、国际社会、企业和个人等纳入其中;多渠道筹措退耕还林还草补偿投入资金,切实转变经济补偿的运作方式;选择相互协调、相互补充的多样化补偿方式;现实中,不充分补偿是常态,实行成本补偿更具可操作性;应对补偿标准进行适当调整,在综合考虑退耕地区自然环境条件、社会经济状况以及林草植被的生态功能等多种因素的基础上,制定分区分级补偿标准:对还生态林应采取长期补偿政策,对还经济林也要适当延长补偿年限。

5Oil and gas were controlled by the structure formed by superposition of tectonic movement in the early and late Hercynian which resulted in palaeogeomorphology and degree of fracture growing. The latter decided the flowing direction of palaeocurrent and the degree of corrosion,which is the main factors of karstification.Especially,the superimposition of palaeostructure and Akekule uplift is the most favorable area for karst and fracture growing.The ubiquitous high angle fracture made all kinds of vugs into a large scale storage,so the fracture-vug system was divided into some blocks in the main oil zone on the plane.
5塔河油田的油气分布受控于海西早、晚期构造运动叠加形成的构造格架,古构造叠加的结果控制了古地貌和裂缝发育强度,古地貌和裂缝发育强度控制了古水系的流动方向及溶蚀深度,它们是岩溶作用发育的主控因素,特别是海西晚期形成的古构造与阿克库勒凸起轴部的叠合部位是岩溶、裂缝最发育的地区,普遍存在的高角度裂缝在三维空间将各类岩溶孔洞连通为大规模的储集体,从而造成主油区大型缝洞系统横向上的分区性。
