蓝莓的栽培技术要点

蓝莓适应性和生命力较强、栽培范围较广，可根据当地的气候条件选择适宜的种类品牌。在北方干旱少雪、灌溉困难的地区不宜发展；在山区或丘陵地带栽培，土壤pH值4.0-5.5，土壤有机质含量8%-12%为宜，确保土壤疏松，排水良好，湿润而不积水。对不完全符合要求的土壤，定植前一定要进行改良。

Sustaining Ecological Integrity with Respect to Climate Change: A Fuzzy Adaptive Management Approach

A fuzzy adaptive management framework is proposed for evaluating the vulnerability of an ecosystem to losing ecological integrity as a result of climate change in an historical period (ex post evaluation) and selecting the best compensatory management action for reducing potential adverse impacts of future climate change on ecological integrity in a future period (ex ante evaluation). The ex post evaluation uses fuzzy logic to test hypotheses about the extent of past ecosystem vulnerability to losing ecological integrity and the ex ante evaluation uses the fuzzy minimax regret criterion to determine the best compensatory management action for alleviating potential adverse impacts of climate change on ecosystem vulnerability to losing ecological integrity in a future period. The framework accounts for uncertainty regarding: (1) the relationship between ecosystem vulnerability to losing ecological integrity and ecosystem resilience; (2) the relationship between ecosystem resilience and the extent to which observed indicators of ecological integrity depart from their thresholds; (3) the extent of future climate change; and (4) the potential impacts of future climate change on ecological integrity and ecosystem resilience. The adaptive management element of the framework involves using the ex post and ex ante evaluations iteratively in consecutive time segments of the future time period to determine if and when it is beneficial to adjust compensatory management actions to climate change. A constructed example is used to demonstrate the framework.

Assessing the ecological security of the Tibetan plateau: methodology and a case study for Lhaze County

A system for assessing the ecological security of Lhaze County in China's Tibetan Autonomous Region was developed using a pressure-state-response model and the analytic hierarchy process. We then used this model to comprehensively evaluate the status of ecological security in Lhaze County. Our results showed that the ecological environment in Lhaze County has deteriorated from an 'early stages of damage status' in the 1980s to 'moderately damaged status' today. This deterioration has become a major barrier to local economic development and social advancement. Natural and social aspects related to the population explosion, resource exploitation, and climate change that led to this ecological deterioration are discussed. Furthermore, we have suggested proposals for improving the ecological environment that include controlling population growth and enhancing the system of laws that protect the environment, upgrading 3 882.6 ha of low-yield farmland, planting 2 425.8, 548.8, and 1 207.4 ha of shelter belts for farmland protection, soil and water conservation, and fuelwood, respectively, and seeding 2 358.1 ha of artificial grassland. In the meantime, we propose strengthening the controls that limit soil and water loss, and optimizing industrial sectors that aspire to achieve high-efficiency, ecologically responsible agriculture.     

初论新疆大农业生态地质环境调查

大农业生态地质环境学是一门集地质、地理、气候、生态、环境、农业等诸多学科为一体的新兴边缘学科。它以地质学为基础,主要开展对土壤、水、大、气候、地理、地质环境和农作物的调查研究,建立土地资源科学评价体系和农作物生态地质环境模式,为政府科学规划、布局、管理土地资源和调整产业结构提供科学依据。展望21世纪,西部大开发和新一轮国土资源大调查给新疆大农业发展带来了难得的机遇,我国加入WTO又面临挑战,机遇和困难并存,地学和农学结合势在必然。开展新疆大农业生态地质环境调查,特别是新疆名优特农产品种植区生态地质调查具有十分广阔的前景。     

Prioritizing ecological and human welfare risks from environmental stresses

The ecological systems of Earth are subjected to a wide array of environmental stresses resulting from human activities. The development of appropriate environmental protection and management policies and the appropriate allocation of resources across environmental stresses require a systematic evaluation of relative risks. The data and methodologies for comprehensive ecological risk assessment do not exist, yet we do have considerable understanding of econological stress-response relationships. A methodology is presented to utilize present knowledge for assignment of relative risks to ecological systems and human welfare from anthropogenic stresses. The resultant priorities, developed for the US Environmental Protection Agency's (EPA) relative risk reduction project, highlight global climate change, habitat alteration, stratospheric ozone depletion, and species depletion as the highest environmental risks, significantly diverging from the present emphasis by EPA and the public on toxic chemical issues. Enhanced attention to ecological issues by EPA and development of ecological risk assessment methodologies that value ecological and economic issues equitably are key recommendations.

Adaptively Managing Wildlife for Climate Change: A Fuzzy Logic Approach

Wildlife managers have little or no control over climate change. However, they may be able to alleviate potential adverse impacts of future climate change by adaptively managing wildlife for climate change. In particular, wildlife managers can evaluate the efficacy of compensatory management actions (CMAs) in alleviating potential adverse impacts of future climate change on wildlife species using probability-based or fuzzy decision rules. Application of probability-based decision rules requires managers to specify certain probabilities, which is not possible when they are uncertain about the relationships between observed and true ecological conditions for a species. Under such uncertainty, the efficacy of CMAs can be evaluated and the best CMA selected using fuzzy decision rules. The latter are described and demonstrated using three constructed cases that assume: (1) a single ecological indicator (e.g., population size for a species) in a single time period; (2) multiple ecological indicators for a species in a single time period; and (3) multiple ecological conditions for a species in multiple time periods.
