The study of the effect of vegetation on snow ablation can be used to predict the snowline, glacier and water level. The snow ablation is observed in the Picea crassifolia, shrub, frost edge and grassland of sunny slope at the altitudes between 2600 and 2700m from 2003 to 2007. The daily variable of snow depth and the change of snow coverage and the sensible heat flux of snow surface are used to determine the snow ablation at Pailugou Basin of Water Conservation Forest in the Qilian Mountains. The observation began with the snowfall in October and ended at the completely ablation of snow in May, and got 1344000 observation data.

Results As the results, there was 6 patients with the ILVT cycle length of (286±38)ms. The indicaed site of EA by noncontact mapping was at the middle septum in 4 patients, and at the inferior septum in 2 patients. Mean time of EA was (48.6±32.8)ms before onset of the surface QRS. The length of conduction pathway was (2.6±0.9)cm. The ablation catheter mapping showed perfect match in at least 11 of 12 leads at the EX (≥11/12), but not at the EA (≤10/12) with pace mapping during sinus rhythm. Purkinje potentials were mapped at EA and CP in all cases, but only one case at EX, and diastolic potentials were mapped at EA in 2 cases during ILVT. All cases were successfully ablated by area ablation at EA or/and line ablation at CP during sinus rhythm. None suffered a recurrence during (12±6) months follow-up.
