川西北高寒草地退化成因及恢复对策

川西北高寒草地是长江和黄河上游重要的生态屏障,在水土保持、生物多样性保育和区域气候调节等方面具有不可替代的作用.川西北高寒草地的严重退化正危及着草地资源的可持续利用和高原生态环境安全.本文借鉴国内外相关研究,综合认为草地生态环境的脆弱性是川西北高寒草地退化的内因,人类不合理的利用和干扰（草地开垦、旅游开发和过度放牧等）是川西北高寒草地退化的主要驱动力,气候变暖、草原鼠虫害频发及草地管理不善等加速了川西北高寒草地的退化.提出了依据草地退化成因,以科技为主导,以草定畜、提高出栏率,轻度和中度退化草地进行草地改良和围栏,重度退化草地进行栽培草地建植,同时结合草地合理开发和鼠、虫害综合治理,加强草地监测、人才建设与加快科技成果推广和转化的恢复举措.

Strategy for screening eucalypts for saline lands

We present a new approach for selecting seed sources of Eucalyptus to be grown on saline land. We evaluated our method using 22 seed sources, 11 tree-form species and 11 mallee-form species. We found that the commonly used strategy of selecting seed sources on the basis of average productivity was inappropriate, as average productivity was poorly correlated with the relationship between productivity and salinity that was actually observed. Using our new approach, we categorized seed sources as salt-sensitive or salt-tolerant based on the strength of the observed relationship between salinity and productivity. Seed sources defined as sensitive were associated with relatively large (−24.8 to −64.2%) productivity losses, while the changes in productivity for tolerant seed sources ranged from −17.1 to 10.5%. On average, reductions in height due to increased salinity were about 30% greater for sensitive seed sources than tolerant ones, although the effect was smaller for mallee-form and greater for tree-form seed sources. The difference between sensitive and tolerant seed sources was similar after 1, 2 and 4 years of growth.

An Ecological Framework for Planning for Forest Health

Concerns for maintaining biodiversity have led to the adoption of ecosystem management as the paradigm for federal land management. This approach will identify desired future conditions as the goal for management, based on ecological objectives for a given landscape. Some management efforts attempt to identify desired future conditions based on existing successional stages as defined by a classification of overstory vegetation types. Such an approach ignores most of the underlying ecological parameters of the landscape, and is inadequate for identifying past disturbance regimes and future successional pathways. An assessment of desired future conditions based on an ecological classification system is essential to overcome these inadequacies. The strategy proposed in this paper uses an appropriate ecological land classification, based on either ecological land types or habitat types, included in a broader hierarchical classification system. It also uses a vegetation map of existing overstory vegetation. These two maps are overlaid to generate polygons of ecological units that can then be used to create an ecosystem diversity matrix. Each polygon (stand) can be evaluated as to its composition and structure relative to its possible placement within the ecosystem diversity matrix through comparisons with historical ranges of variability. The overall ecosystem diversity matrix can then be examined in terms of the distribution of successional stages within each habitat type or ecological land type. The goal should be to maintain at least adequate ecological representation of all successional stages within each habitat type that occurred historically, based on past disturbance regimes. Adequate ecological representation is defined as sufficient size and distribution of inherent ecosystems to maintain viable populations of all endemic species dependent on these ecosystems. This approach can maintain and enhance regional biodiversity, but also maintain flexibility in land management options.
