摘要

以土地生态景观格局优化为基础

以功能定位与建设为目标

进行了上黄示范区生态经济功能区规划与建设

提出了生态保护功能区、旱作农业功能区和高效生态农业功能区的景观生态特征、主体功能、主体模式和指标要求。通过5a的生态经济功能区建设

上黄示范区2010年人均收入达到4470元

人均产粮480kg;植被覆盖率达到70.3%

土壤侵蚀模数小于500t/(km

.a)

初步实现了生态保护区"保土、理水、储碳和植物资源保育利用"

旱作农业区"土壤培肥、粮食增产、土地生产力提高"

高效生态农业区"光热水资源优化组合、低碳高效、社会生态经济和谐发展"的功能目标。建立的功能区模式和相应的建设技术体系

将为宁南及黄土丘陵区乡村一级为基本单元的生态经济功能区规划建设提供有益借鉴。

Abstract

The regionalization and construction of eco-economic functional areas were made based on land uses and their functions in Shanghuang demonstration area.The ecological characteristics of landscape

functions

models

and indexes for the ecological protection area

dryland farming area

and efficient eco-agricultural area were presented.After 5 years of the construction of the functional areas

per capita income and per capita grain production capability in the demonstration area reached 4 470 RMB and 480 kg

respectively.Vegetation coverage and soil erosion module in 2010 reached 70.3% and 500 t/(km2·a)

respectively.The initial targets for the three functional areas have been accomplished.The models and their technological systems of suburb eco-agriculture and eco-homeland established in Shanghuang demonstration area may be useful to the regionalization and construction of eco-economy functional areas at town and village scales in the loess hilly-gully region of southern Ningxia Hui Autonomous Region.
