土地利用

In addition, the adjustment of economy structure and the policy about land are the primary driving factors for the conversion among farmland, woodland and grassland; the advantage of economy around central cities and the traffic along river are the leading driving factors for towns outstretching; pursuing economy profit is the significant driving factor for water outstretching; the land policy is the main driving factor for water shrank.

另外，农村经济结构调整和有关耕地政策的出台是耕地、林地与草地相互转换区土地利用变化的主要驱动因素；中心城市对周围区域经济的带动作用和沿江区域特殊的交通优势是城镇扩张区的主要驱动因素；经济利益的驱动是水域扩张区的主要驱动因素；耕地政策是水域缩减区的主要驱动因素。

Following the further improvement of market economic system in China,the social structure becomes pluralized,the demands and motivations of land use are diversified,and the behavior of land use planning turns complicated.

随着中国市场经济体制改革的不断深入，社会主体构成多元化，用地需求、用地动机呈现多样化，土地利用规划行为更加复杂。

The purpose of the paper is to find out reasonable methods to evaluate on urban land use potentialities.

研究目的：研究合理的城镇土地利用潜力评价方法。

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。

According to the history of LUCC evolution in 20 century in Northeast China Region, demonstrating the feasibility of digital reestablishing seven phases and 1:250000 scale data-base in this area.

根据东北地区20世纪的土地利用演变的历史，对东北地区20世纪数字重建的七个时间断面和1：25万的数据库的可行性进行了论证。

On the basis of the analysis of physicochemical properties of soil, analyzes variance characters of soil physical properties and nutrient properties in different land use ways and slope locations in the western edge mountains of Sichuan basin, and the results indicate that, in the respect of soil physical properties, it is either the soil structure coefficient or the degree of aggregation that is contained in farm land is obviously less than that is contained in reforested land and waste land, and because of the effects that forest crop root system and forest floor take, the soil physical properties of forest plantation is far better.

在土壤理化指标测定基础上，分析了四川盆地西缘中低山坡地不同土地利用方式和坡位下土壤物理性质与养分性质的分异特征，结果表明：土壤物理性质方面，耕作土壤的结构系数和团聚度明显低于人工林和荒草地，人工林由于林木根系和枯枝落叶层的作用，土壤物理性状明显较好。

Soil sampling is carried on on the typical slopes, and the mountain slope location that is being researched is divided into three parts: upper slope, middle slope, lower slope, and three land use ways are selected respectively in each slope location(altitude, slope gradient and aspect are same on the whole): farm land,, reforested land, waste land are taken as sampling sites.

土壤采样选取典型坡面进行，把研究的山体坡位分为3个部分：上坡位、中坡位、下坡位，在每个坡位(海拔高度、坡度及坡向基本一致)分别选取3种土地利用方式：坡耕地、人工林、荒草地作为采样点。

In the paper, the author establish the evaluation system between the "two planing" based on the reintegrating and perfecting of the spatial planning system in our country and the reforming requirement to the sub-planning of spatial planing—the "two planing" from the change of precondition of the making of planning, through which to indicate the complicated contradictive relation between the " two planning ", to quantificationally appraise the present maturity degree and to guide the developing direction to the " two planning ". the author try to find out the two planning's reform direction and emphases in aftertime though out putting the evaluation system between the "two planing" into the sample city regional practice. In the end of this paper, the division and the collaboration mechanisms of the "two planing" have been discussed under the future perfect spatial planning system, also the division and the collaboration two strategies of the "two planing" based on current situation development of planning and the future perfect spatial planning system have been pointed out.
