开花前后变水条件对春小麦的补偿效应

在防雨棚内的盆栽实验条件下，研究了4种梯度的10种不分组合对红芒麦和宁春10号产量及耗水量等的影响。结果表明，试验期间充分灌水，轻度，中度，重度干旱处理，随着干旱程度的加剧，株高，干物质积累，产量，耗水量都逐渐减少；红芒麦灌浆期不同程度的,匀有利于产量的形成，促进物质运输，提高千粒重，同时减少水分消耗，提高WUE；孕穗期干旱处理后，灌浆期复水，会造成减产，和灌浆期相比，孕穗期是水分的敏感的时期，而灌浆期对水分亏缺不敏感，两种小麦相比较，宁春10号耗水量大，产量低，抗旱性较强，图2表2参7

从施肥和耕作制看耕地的可持续利用

加强农业基础地位，实现农业的可持续发展，是关系到国计民生的大事。耕地是农业的基础，耕地的可持续利用是农业可持续发展的关键。近年来，有些地方盲目追求经济效益，实行连年种植一种经济作物，重化肥，轻土杂肥及环境污染等因素，造成土壤酸化，肥力下降，土壤资源遭受破坏。如何保护好耕地，防止土壤退化，实现耕地的可持续利用，是农业生产中急待解决的问题。东莞市从1984年冬开始，对全市所有耕地进行分类，选取8个有代表性的土壤地力监测点，进行地力跟踪，至今已有15年。经过15年的监测，发现合理的施肥和耕作制，有利于保护土壤…

Assessing the impact of the U.S. Endangered Species Act recovery planning guidelines on managing threats for listed species

The Endangered Species Act (ESA) of the United States was enacted in 1973 to prevent the extinction of species. Recovery plans, required by 1988 amendments to the ESA, play an important role in organizing these efforts to protect and recover species. To improve the use of science in the recovery planning process, the Society for Conservation Biology (SCB) commissioned an independent review of endangered species recovery planning in 1999. From these findings, the SCB made key recommendations for how management agencies could improve the recovery planning process, after which the U.S. Fish and Wildlife Service and the National Marine Fisheries Service redrafted their recovery planning guidelines. One important recommendation called for recovery plans to make threats a primary focus, including organizing and prioritizing recovery tasks for threat abatement. We sought to determine the extent to which results from the SCB study were incorporated into these new guidelines and whether the SCB recommendations regarding threats manifested in recovery plans written under the new guidelines. Recovery planning guidelines generally incorporated the SCB recommendations, including those for managing threats. However, although recent recovery plans have improved in their treatment of threats, many fail to adequately incorporate threat monitoring. This failure suggests that developing clear guidelines for monitoring should be an important priority in improving ESA recovery planning.

Transboundary maritime spatial planning: a Baltic Sea perspective

Maritime Spatial Planning is a new form of spatial planning emerging at the intersection of expanding demands for commercial use of marine space and increasing concerns for marine ecosystems. Many coastal countries around Europe are presently engaged in this field -not only by their national activities but also cooperating across borders through transboundary dialogue, joint strategies and even considering joint planning. In the Baltic Sea region transboundary cooperation takes all these forms. Such activities, including the Plan Bothnia pilot planning of the Bothnian Sea between Sweden and Finland, bring into surface differences in planning procedures and approaches, views on the environment, compatibilities of geographical data and the general complexity of the international-national legal framework. Creativity and transparent, accountable procedures are needed to ensure that such initiatives are both useful and legitimate.

Incorporating connectivity into conservation planning for the optimal representation of multiple species and ecosystem services

Conservation planning tends to focus on protecting species’ ranges or landscape connectivity but seldom both—particularly in the case of diverse taxonomic assemblages and multiple planning goals. Therefore, information on potential trade-offs between maintaining landscape connectivity and achieving other conservation objectives is lacking. We developed an optimization approach to prioritize the maximal protection of species’ ranges, ecosystem types, and forest carbon stocks, while also including habitat connectivity for range-shifting species and dispersal corridors to link protected area. We applied our approach to Sabah, Malaysia, where the state government mandated an increase in protected-area coverage of approximately 305,000 ha but did not specify where new protected areas should be. Compared with a conservation planning approach that did not incorporate the 2 connectivity features, our approach increased the protection of dispersal corridors and elevational connectivity by 13% and 21%, respectively. Coverage of vertebrate and plant species’ ranges and forest types were the same whether connectivity was included or excluded. Our approach protected 2% less forest carbon and 3% less butterfly range than when connectivity features were not included. Hence, the inclusion of connectivity into conservation planning can generate large increases in the protection of landscape connectivity with minimal loss of representation of other conservation targets.

Quantitative Pollution Spill Risk Assessment: Using A Gis-Based System

Federal and State agencies have recently advocated risk-based analysis as a mechanism for advancing regulatory reform and safety determination in marine systems. the present investigation promotes this objective through the development of risk-based environmental planning strategies for oil spill contingency plans. This alternative approach to contingency planning departs from conventional methodology by employing quantitative risk assessment methods to identify hazardous oil spill zones and sensitive environmental areas, R_o and R_e respectively. the product of this conversion is referenced on a single “Risk” layer within a Geographic Information System (GIS) framework allowing coastal managers to evaluate natural resource data with associated elements of oil spill risk. As a new tool for coastal pollution management, risk-based environmental planning strategies have shown potential for evolving more efficient oil spill contingency plans.
