Study on Restoration and Reestablishment for Green Field of Degenerative Turf in Base in Tazhi

首次提出了退化草坪绿地恢复与重建的概念和经济技术要点。对塔指生活基地轻度退化草坪绿化施用恢复性生态技术后，整体草坪比退化时的质量提高了一个档次，投入恢复成本0．54元／m^2·年，仅占养护费的4．2％。对中、重度退化草坪施用一套重建生态工程技术后，重建草坪60天成坪，其质量水平比退化时提高了2-3个档次，重建投入成本6．88元／m^2，占原建设成本的40．7％。

Firstly put foword restorative and reestablishing comcept and economic and technical essentials for green field of degenerative turf. After lightess degree in green field of degenerative turf used resunptive and ecological and engineering technique, the quality of whole turf raised one-grade than that of degenerative turf, invested cost of restoration is of 0.54 yuan/m^2/year, only account for 4.2% of conservative cost. After middle and heaviness degree in green fled of degenerative turf used a whole set of reestablishded and ecological and engineered technique, the reestablishded turf is forming turf of 60 days, its quality raised two and three-grade than that of degenerative turf, invested cost of restoration is of 6.88 yuan/m^2, make up 40.7% of the original cost.
