Taking the administrative villages as units, a comprehensive and detailed survey was made to attain the rich and reliable data, including the information about the status of the land use, the relationship of the land supply and demand, the living standards of farmers and the minimum of urban resident living guarantee and so on. Then the estimating system was established. Afterwards, basing the survey and the system, the character of each unit was transfer into data. And, utilizing the frequency law, the whole county was divided into four expropriation land blocks. The area was measured and the map, showing the differences between blocks, of the Arable Land Blocks for expropriation of Siyang was protracted by the method of GIS. Finally, the land expropriation price is calculated by agricultural land economical function compensate method and urban construction land criterion price avulse method, then the price was tested by expropriation case comparison method. It is beneficial not only for protecting farmers rights and interests, but also for link up with the current land compensate standard, so this way to calculate the land expropriate price is more reasonably.

以行政村为基本单元，对该地区的农用地利用现状、土地供求关系、农民生活水平扣城镇居民最低生活保障水平等情况进行了调查，建立征地区片价格评价体系，根据每个评价单元的综合评价分值，运用总分频率法将全县分为四个区片，并对各级区片进行面积量算，借助地理信息技术绘制了《泗阳县农用地征地区片价格分布图》，显化了农用地征地区片价格的空间分布及其差异，最后运用农用地经济功能价格补偿法和城镇建设用地基准地价剥离法综合测算农用地征地区片价格，并用征地案例比较法的测算结果加以比较验证，证明此测算结果相对更加科学合理，既有利于保障被征地农民的合法权益，又有利于与现行的征地补偿标准相衔接。

First of all, as the forests disappeared, the propagation decreased, while some kinds of plants and animals were even close to deracination or had already died out. Next, the natural disasters, such as flood, drought, and tornado, etc. broke out more frequently and strongly. Again, without the protection by forests, soil erosion and fertility decline together with other problems appeared. Finally, forest vicissitude also had negative effect to social economy and people's lives.

首先是由于森林面积的减少，导致一些森林动植物的数量减少，濒临灭绝，甚至消失；其次，森林的变迁导致海南岛水灾、旱灾和风灾等自然灾害发生次数增加，强度加大；再次，土地失去森林的保护而引发严重的水土流失和土壤肥力下降等种种问题；最后，森林的变迁还对社会经济及人们的生活产生不利的影响。

Assuming that half of the carbon loss in the degraded terrestrial ecosystem in current forest and grass areas are restored during the next 50 years or so, the terrestrial ecosystem in China may sequestrate～12.0Pg of organic carbon from the atmosphere, which represents a considerable offset to the industry's CO〓 emission.

5在现有的气候条件下，未来50年或更长的时间上，如果我们能通过有效的土地利用措施使我国现有林地和草地面积上的生态系统碳损失量恢复其中的1/2，那么我国陆地生态系统将具有～12.0Pg C的碳汇潜力。

In view of the vast range of mountainous and hilly areas,a unique characteristic of Fujian topography,it especially analyses the effects of topograph on climate and soil nutrient storage.According to the mechanism of how the grain produtivity comes into being,this paper achieves the calculation of potential grain productivity in variou...

尤其针对福建山地丘陵面积大的特点，专门分析了地形因素对气候及土壤养分存贮状况的影响，根据作物生产力形成的机理，采用光、温、水、土逐项衰减的方法，计算了福建省各地以水稻为代表的粮食作物的土地生产潜力，并据此提出了发展福建粮食生产的相应建议。

By analyzing the cultivated land data from different sources in different phases after 1949,the paper considers the statistics with more errors happens during 1960-1985.According to the systematic data on land use gathered in the 1996 survey,based on reverse deduction of the cultivated land area from 1986 to 1996,and deduction of the cultivated land area from 1960 to 1985 by stages by employing yield of grain,this paper redescribed the actual changing trend and character of Chinese cultivated land and analyzed the driving force of the policy relative to cultivated land to cultivated land area change.

针对该问题，论文对1949～2003年不同时期不同来源的耕地数据系列进行分析，认为统计数据存在问题较多的时期为1960～1985年，并采用粮食产量对耕地面积进行了分时期的反演，对于1986～1996年间的耕地数量则按照全国土地利用详查统一到1996年的结果再进行反推，由此重新刻画建国以来中国耕地资源数量变化的趋势和特征，并结合不同时段耕地相关政策对耕地数量变化的驱动作用进行分析。
