| 摘 要： | 为了比较退耕还林工程中应用保水剂造林和常规造林成本,以河北省张家口市崇礼县和康保县为例,对其应用保水剂造林成本进行了核算,结果表明,利用保水剂造林成本较高.但此方法可以提高造林的成活率,减少补植工作量或重造次数,也就相应降低了造林成本.保水剂作用发挥是在有降水或者提前吸水的条件下,因而选用保水剂造林时,要因地而异,选择合适的保水剂类型.只有掌握了使用比例、方法,选好造林季节,保水剂造林效果才能保证,成本方能降低.

| Abstract: | This study was conducted to compare the cost of for estation using super absorbent polymers (SAP) and the cost of conventional for estation in the converting cropland to forest program. Chong li County and Kangbao County were taken as two examples to estimate sylvicultural cost of SAP. Results showed that the sylvicultural cost of SAP was higher than that of conventional planting.However, the survival rate of forestation using SAP was increased and the cost of replanting was reduced. Thus, the sylvicultural cost can be reduced relatively. SAP function was affected by moisture condition because SAP can not product water. When SAP was used in forestation, soiltype, SAP type, dosage, method, and forestation season should be considered. |
