【摘要】 在陆相单断盆地中，如果不考虑湖水总体积的改变，当断块发生掀斜时，因非均衡构造沉降会发生以下五种变化：（１）缓坡湖退；（２）陡坡湖进；（３）湖心湖水变深；（４）湖面变窄；（５）可容纳空间增大。若干实例现已初步证实了这种作用的影响更多还原

【Abstract】 Relative changes of lake level in continental basins are complicated controlled by multiple variables such as tectonic subsidence, absolute lake level change, deposit supply and climate.Perhaps the water level of lake basin is more significantly influenced by tectonic variation than that of sea basin because of the nonbalanced tectonic subsidence. With the total water volume of lake neglected, five changes of single faulted basins would happen while blocks tilt:(1)regression at gentle slope;(2)transgression at steep slope;(3)deepening of water body in the centre of a lake;(4)broadness of lake level and (5)growth of capacity.Some practical data have proven these preliminary conclusions.更多还原
