Ecological Regionalization of Suitable Trees, Shrubs and Herbages for Vegetation Restoration in the Farming-Pastoral Zone of Northern China
To provide materials for the selection of plant species for vegetation restoration and re-construction in the farming-pastoral zone in northern China, where the eco-environment has been al-ready deteriorated by over-farming and over-grazing, the suitable trees, shrubs and herbages were examined,screened and identified under the guidance of four principles of taking precedence for ecologicalconservation, being beneficial to economic production, matching species (trees, shrubs and herbages)with the site, and giving consideration to the integrity of local administrative division. According to the keyecological factors that determine species growth and distribution in the zone, i.e., the lowest daily meantemperature in a year, annual accumulated temperature, and water regimes represented by the moistindex, the ratio between annual rainfall and accumulated temperature (＞0℃), as well as the soil typeinfluenced by climate, surface substances and landform, the farming-pastoral zone was regionalized intoseven parts: (Ⅰ) Western Songliao Plain and Da Hinggan Mountain Region; (Ⅱ) Upper Liaohe River SandyRegion; (Ⅲ) Mid-Eastern Nei Mongol Plateau and Northwestern Heibei Mountain Region; (Ⅳ) Luliang,Taihang and Yanshan Mountain Region; (Ⅴ) Ordos Plateau Sandy Region; (Ⅵ) Northern Shaanxi toEastern Gansu Loess Plateau Region; and (Ⅶ) Mid Gansu to Eastern Qinghai Plateau Loess Region. Andthe suitable trees, shrubs and herbages for each region were selected and tabularly introduced in detail.
