长江上游生态环境和社会经济条件研究与评价

The Studies and Assessment for Ecological Environment and Social Economic Conditions in the Upper Reaches of the Changjiang River.

以乌江和川江流域为研究范围,以系统理论为指导,从综合观点出发,对自然和社会经济环境特征及其对森林影响的评价、生态经济分区与生态经济防护林体系宏观布局,以及不同生态经济区防护林体系建设前景的定量预测这三个层次开展了研究工作。利用现代化技术,获取了大量技术资料和建立定量定性评价模型,为长江上游防护林体系建设工程的可行性和宏观调控技术方案的制定提供了重要的科学依据并对工程的实施具有指导作用。

The area is distributed in the watersheds of the Wujiang River and the Changjiang River which includes the Jialingjiang River, the Qujiang River, the Fujiang River, the Tuojiang River and the upper reaches of Minjiang River in the upper reaches of the Changjiang River. Applied the integrated standpoint under guidance of the theory of systems science, the characteristics of natural and social economic environment and the assessment for their effects on the forests, ecological econoimc divisions and macroscopic overall arrangement of the ecology-economic protection forest system, and quantitative forecast for development prospects of the protection forests in each of the ecological economic divisions have been studied. A great quantity of technological data, and quantitative and qualitative assess- ment models have been gained, which have provided important scientific basis with guidance significance for construetion project of the protection forest system in the upper reaches of the Changjiang River.
