- 摘要:
- 贵州是一个亚热带山区省份，73%的土地在喀斯特地区范围内，生态系统脆弱，水土流失严重。为保护土壤资源，于1991～1994年开展了本项试验研究。研究结果表明，在17～23°的坡地上，裸地处理年径流量和土壤侵蚀量分别达3778～5503m3/hm2和1194lt/km2；传统种植法土壤侵蚀量达5779～9545t/（km2·a），随水土流失所带走的养分（N、P2O、K2O）达947～1616kg/（hm2·a）。特别是条带种植法（生物梯化）保护水土资源的显著效果，在栅篱作物种植以后，条带种植处理与传统种植法相比较，1991～1994年其土壤侵蚀量分别减少19.3%、82.2%、77.9%与100.0%，是一项经济有效有发展前景的水土保持增产措施。
- Abstract:
- Guizhou is a subtropical mountainous province, and approximately 73 per cent ofwhich are karst areas. The ecosystem in these areas is very fragile and the soil and water lossesare extremely severe. In order to protect soil resource, the research was conducted in 1991~1994, The result indicated that, on the sloping upland with gradient of 30%~40%, the runoffof bare land reached 3 778~5 503m3/hm2 and the soil loss reached 11 914t/km2. For farmers’ practice,the soil loss was 5 779~9 545t/(km2·a) and the lost nutrients (N,P2O5,K2O)in soiland water reached 947~1 616kg/hm2·a. Especially, the treatment of alley cropping was con-spicuous for its striking effect on the protection of soil and water resources. After thehedgerow strips were set up, the soil erosion from alley cropping was decreased to 19.3%,82.2%, 77.9% and 1OO% respectively compared with farmers’ practice in 1991~1994.
