The worsening environmental conditions are becoming a threat to peoples livelihoodand economies. Critical issues include desertification and excessive carbon emission， thelatter leading to a rising sea level and the greenhouse effect. Restoring desert is an impor?tant method to help cope with these issues. When it comes to desert reclamation， plantingtrees by using robot clusters（組）is an innovative， effective practice.

Planting trees in the desert， however， faces several hurdles. First， the time frame isnarrow. In deserted areas， only the short span of spring is suitable for growing trees.Second， the efficiency of manual （體力的） planting is low. Take pit digging as an example.This seemingly simple step takes about 25 minutes for one person to complete. Third，even machine?aided planting requires manual supervision. Previously， there was no solu?tion to around?the?clock， fully unattended operation. Machines werent able to automati?cally plan the route or intelligently bypass obstacles.

Teachers and students from East China Normal University （ECNU） have developed adesert governance robot based on Huaweis Atlas 200 DK AI Developer Kit. The robot is ca?pable of visual analysis and can automatically determine the vegetation and obstacles to beavoided in the desert to complete operations such as pit digging， planting， and watering.This solution makes massive tree planting really unattended and around?the?clock. The so?lution plants trees faster and achieves a higher survival rate for the trees， helping reclaimdesert at greater efficiency.

Huawei Atlas 200 DK is an integrated device for AI developers. It supports 16 TOPSINT8 and provides hardware interfaces （接口） such as the USB port. It also includes agraphical software development environment， helping developers quickly develop AI appli?cations.

Zhang Xinyu， associate professor of ECNU and head of the Desert Governance RobotProject， said，“Large?scale tree planting with robots is a future trend. This solution can helpus make great progress in ecology restoration and cope more effectively with global warm?ing.”

Ⅰ. Difficult sentence in the text

The robot is capable of visual analysis and can automatically determine the vegetationand obstacles to be avoided in the desert to complete operations such as pit digging，planting， and watering. 這種機(jī)器人具有視覺分析的能力，它能夠自動(dòng)識(shí)別并避開沙漠中的植被和障礙物，從而完成挖坑、種樹、澆水等一系列動(dòng)作。

【點(diǎn)石成金】本句中，第二個(gè)and 連接動(dòng)詞determine 的兩個(gè)賓語，不定式to beavoided 是后置定語，to complete...watering是目的狀語。
