Firstly, electrization knowledge related to the research is introduced. After a deep study on various contact loss detection techniques, especially on the electric arcs detection techniques, we draw the conclusion that the untouched detection technique based on phototube sensor can acquire exact contact loss information, and will to be the leading technique for contact loss measurement in future. Secondly, combining with the special railways system in our country, we analyze the cause of the arcs, and the influence on the power supply system and the on board traction drive due to the arcs in detail, and study the arcs' spectrum characteristic. We also analyze detecting principles and put forward with a method - using phototube sensor to detect the contact loss arcs, conceive the configurations and detection flows of the measurement.

The results show that rising of groundwater levels after water transportation plays an important role in the decreasing in the crown loss of Populus euphratica, and the crown loss of Populus euphratica gradually increases with increasing distance from the river course. The trees crown loss was less than 10%, which mainly was distributed within 100 metres to each side from the river course. The proportion of crown loss of overmature and effete forests were 50%-75% within 200 to 400 metres.

应急生态输水后地下水位的抬升对胡杨树冠疏失度的降低产生一定的作用；总体上，胡杨的树冠疏失度随着离河道距离的增加逐步增大，而且离河道越远，疏失度增加的程度就越大；树冠疏失度小于10%的旺盛胡杨主要分布在离河道100m之内，其中多以疏失度少于50%的长势较好的胡杨为主。
