Considerations on the lake morphometry changes occurred in Lacul ?tiucii (Cluj County, Romania) and safeguard measures proposed

摘要

In order to quantify as accurately as possible recent transformations of Lacul ?tiucii (PikeLake) reservation in the Transylvanian Plain, this work has been aimed at portraying the lake’smorphometric evolution throughout the last fifty years and at finding the most effective methods to stopor reduce the siltation phenomena which threaten this priceless heritage. To the end, a set of correctivemeasures meant to slow down the fast-paced silting up process affecting this lake has been envisaged.The human impact on the natural environment dates back to immemorial time, being apparent eversince the onset of the human civilization. However, anthropic transformations became more and moreprevalent as the human species evolved and as it evolutionary features became more diversified.Humans have been exerting an ever-increasing impact on the nature, as a result of the synergisticinfluence of several aggravating factors, as follows: occupation of all biotopes deemed to providefavorable conditions for human life and human activities; continuous improvement and breakthroughs inthe field of natural resource extraction/exploitation (both underground and aboveground); dramaticincrease in human population growth rates (Giurc?neanu 1982). The situation was made worse by theincreasingly irresponsible behavior of humans and by their selfish belief that they have the right to treatand exploit nature as they see fit, as long as this generates lucrative results (Soran & Borcea 1985). Thebrief review of all the factors mentioned above provides an accurate representation of the continuousdegradation of our natural environment, including the natural reservation Lacul ?tiucii, on which thecurrent study focuses.
