The configuration method comprises selection of plant hedge planting type, land consolidation, plant hedge planting, late stage watering management, later stage pruning management forming plant hedge configuration form of pyracantha fortuneana, climbers+shrubs+herbs, climbers+small trees+herbs, herbs+shrubs; the plant hedge configuration form of pyracantha fortuneana, climbers+shrubs+herbs, climbers+small trees+herbs, herbs+shrubs is obtained in the method, control of soil erosion is conducted concerning light-potentially rocky desertification in karst region, the surface coverage is increased, the surface flow rate is reduced, the soil erosion is decreased, and the soil fertility is improved and preserved. Cash crops such as Hypericum monogynum, pyracantha fortuneana, Trifolium repens, and Prunus Humilis Bunge are planted. Crop yield is high, terrace stability and economic incomes of peasants are improved, the usage rate of the soil in karst region is increased, and the method is especially accepted by peasants in light-potentially rocky desertification environment.

The invention provides an offshore oil-gas subsea pipeline protection device. The device comprises a trapezoidal long frame, bionic waterweeds, a U-shaped pile, rolling assemblies and a cathode protection assembly, the top of the trapezoidal long frame is fixedly connected with the U-shaped pile through a second transverse frame, a pillow plate is arranged in the trapezoidal long frame, a set of guide rails are installed on the pillow plate, and an arch-shaped plate is fixedly connected to the guide rails. The bionic waterweeds are installed on a seabed, first transverse frames are installed at the two sides of the U-shaped pile, and the first transverse frames are fixedly connected with the two side edges of the arch-shaped plate through damping pieces. Pipelines are fixedly connected with each other through a flexible pipe, a pair of rolling assemblies are arranged in the flexible pipe, each rolling assembly comprises a ball and a sleeve, the sleeves are rotatably connected with theflexible pipe through the balls and pipe inner cavities, and the cathode protection assembly is fixed in the pipelines through a mounting plate. The device is suitable for protecting the offshore oil-gas subsea pipelines, scouring of water flow to the pipelines can be effectively reduced, eddy current oscillation is reduced, and chemical corrosion and the heat effect in the pipelines can be resisted.
