摘要
退耕还林是国家为保护生态环境、治理水土流失的一项重大举措,但在广大的基层农村,还缺乏有效的技术支持手段。“3S”技术是集遥感、全球定位与地理信息系统于一体的高新技术手段,可以为退耕还林提供强有力的技术支持。就“3S”技术在梅州市退耕还林应用中的设备选用、技术路线、基本过程与方法等进行了探讨,对基层退耕还林工作的开展起到一定的指导作用。
It is one of the most important ways for protecting the ecosystem environment and soil and water conservation by converting cultivated land to forest. But in the countries, the technique means are short of solving it. The 3S technology, an integrated technology of GPS, RS and GIS, is a high-tech means,can give support for converting cultivated land to forest. Under the support of 3S technology, selecting of equipments , general thoughts and the principle methods and procedure of its application in converting from farmland to forest are discussed, which plays an important role in converting cultivated land to forest in the future.
