| 摘要: |
| 【目的】对椰糠基质、稻草秸秆、麦草、芦苇秸秆和玉米秸秆等农业废弃物粉碎处理，制作成一种新型的生态毯，为生态环境的治理提供新的方法与思路。【方法】经前期试验筛选出材料，设计制作了12种生态毯配置，T1（麦草+椰糠）、T2（玉米秸秆+椰糠）、T3（（稻草、玉米秸秆、麦草）+椰糠+玉米秸秆）、T4（玉米秸秆+（椰糠、麦草）+（稻草、玉米秸秆、芦苇））、T5（玉米秸秆+椰糠+芦苇）、T6（椰糠+麦草+芦苇）、T7（（玉米秸秆、椰糠）+玉米秸秆+（玉米秸秆、椰糠））、T8（稻草+椰糠+麦草）、T9（玉米秸秆+麦草+芦苇）、T10（玉米秸秆+椰糠+麦草）、T11（玉米秸秆+（玉米秸秆、椰糠、麦草）+玉米秸秆）、T12（玉米秸秆），分析铺设生态毯对表层土壤含水率的影响。【结果】生态毯对土壤含水率有非常好的保持作用和抑制土壤水蒸发的作用。在与人工林下的枯落物比较中生态毯的最大平均持水率达到人工林最大平均持水率的2.07倍。【结论】总结了生态毯的现实应用场景与方法，在荒漠化和沙漠的治理中，选择配置T4、T5、T12配合草方格使用防止风力搬移的同时并在表面覆土。在一般地区没有特殊生态治理要求时可采用配置T12、T4来保持土壤含水率。山林裸地的恢复建议选择配置T1、T4、T8。在平均降水量大且易发洪水的地区建议选择配置T1、T4、T8。 |

| Abstract: |
| 【Objective】Coconut chaff matrix, rice straw, wheat straw, reed straw and corn straw were used to make a new type of ecological blanket after crushing treatment, which provided new methods and ideas for the treatment of ecological environment. 【Method】12 kinds of ecological blanket configuration were designed and made, and the effect of laying ecological blanket on surface soil moisture content was analyzed. 【Result】In the data processing, it was found that the ecological blanket had a very good effect on maintaining soil moisture content and inhibiting soil water evaporation. Compared with the litter under the plantation, the maximum average water holding rate of the ecological blanket was 2.07 times that of the maximum average water holding rate of the plantation. 【Conclusion】 The practical application scenarios and methods of ecological blanket are summarized. In the treatment of desertification and desert, T4, T5 and T12 are selected to cooperate with grass grids to prevent wind movement and cover soil on the surface. When there is no special ecological management requirements in general areas, T12 and T4 can be used to maintain soil water content. It is suggested that T1, T4 and T8 should be selected for the restoration of bare land in mountain forests. If the average rainfall is large and prone to flood areas recommended configuration T1, T4, T8. |
