浙江省的新构造运动与农用地分布规律

从地貌和沉积物分析，浙江省新构造运动表现为西南强烈上升，往东北上渐减，至杭州湾两岸转为下沉，此外西北山区上升，海岸带下沉，一些构造盆地内相对下沉，这些情况与莫霍面等深线图的反映十分符合，说明新构造运动的动力来自地壳深层。不同新构造运动性质的区域内，农用地面积比率、农用地内的结构特征明显不同；各地耕地占总面积的百分比，在大河各河段、滨海各岸段、不同位置的海岛、不同盆地的所在区，均是有规律的变化，也都反映了新构造运动的作用。新构造运动还使地表水土流失与农业经济发展的地理分布很有规律。这些都说明作为地球内力重要部分的新构造运动，能强烈影响地表的生态环境。

Neotectonic Movement and the Distributional order of Agricultural land in Zhejiang Province

In Zhejiang province the place with neotectonic strongest uplifting is situated in southwestern mountain area. From there to the northeastem ward uplifting range decreases gradually and neotectonic movement changes into subsiding in the area by the sides of Hangzhou Bay. Besides obviously in the neotectonic movement coastal region subsides and northwestern area uplifts.All of those mentioned above can be recongnized by the geomorphologic and sedimentary analysis. Moreover they can be rerealed on the bathymetric map of tgedogic Moho depth.This paper discnssed that under the inflaences of neotectonic movement the distributioual order of following items: percentage of agricultural land area, structare of agricultural land, percentage of cultivated land are in different geologic environment, soil erosion , development of agricultaral econmics.All of these distributional orders showed that the neotectonic movement as a important earth endogenic force can inflaence the whole ecologic environment of land surface.
