The land use pattern had changed by a relatively large margin in Neijiang city from 1997 to 2005. The main tendency of this change is that with remarkable reduction of cultivated land that decreased by 9936.11hm~2, unutilized land and water area, while garden land, forest land that increased by 7032.23 hm~2, grass land and building land increased notably. And during the research time, the speed of land use type change reduced from garden land, traffic land, forest land, residential areas and industrial and minings land, cultivated land, unutilized land to water area. The main trend of general dynamic degree changed from progressive increase to degression. From the analyses of land use diversion matrix, we know resulting in the quantity change of land use was that cultivated land being occupied by construction,adjustment in structure of agriculture and the implementation of the national reforesting formerly cultivated land policy in Neijiang city.
结果表明:1997~2005年间,土地利用类型发生较大幅度变化,总体上呈现耕地、未利用地、水域面积显著减小和园地、林地、牧草地、建设用地面积增大的趋势,其中耕地面积减幅最大,达9936.11hm~2,林地增幅最大,达7032.23 hm~2;土地利用类型变化速度依次为园地>交通用地>林地>耕地>居民点及工矿用地>未利用地>水域,其中园地为2.67%,水域为-0.01%,综合土地利用动态度呈现先递增后递减的趋势;从土地利用类型转移矩阵分析得出,建设用地占用耕地、农业结构内部调整、&退耕还林&是导致内江市土地利用类型数量变化的重要原因。

Second, considering the influence of well resistance, smear effect and structure breakage of thick soft clay, the equivalent calculation method is proposed. That is, the partially penetrating sand drain ground is viewed as the double-layered ground, and its consolidation is analyzed with 1-D consolidation theory, through the transformation from 3-D consolidation to 1-D consolidation in the region of sand drain. This can overcome the disadvantage that the excess pore water is discontinuous between the region of sand drain and under-lying soft layer. To the double-layered ground, based on the consolidation mechanism under surcharge, the excess pore water pressure calculation formula is deduced under the condition of multilevel equably loading or unloading, which perfects the consolidation theory.
