为了调查冬麦田和不同年龄生态补偿区甲虫群落结构和物种多样性,从2003年7到10月和2004年5到6月在瑞士农业区周围不同景观中进行了实地调查,并采用对应及典范对应分析方法,对冬麦田和1~4a不同年龄阶段的野花地中的甲虫群落结构及物种... 为了调查冬麦田和不同年龄生态补偿区甲虫群落结构和物种多样性,从2003年7到10月和2004年5到6月在瑞士农业区周围不同景观中进行了实地调查,并采用对应及典范对应分析方法,对冬麦田和1~4a不同年龄阶段的野花地中的甲虫群落结构及物种多样性进行了比较系统的研究.结果,共捕甲虫6009只,分别属于150种,25科,其中,麦田共计38种445个体,1~4a不同年龄的野花地中分别计46种,2760个体,81种,1325个体,73种,668个体,75种,811个体.根据食性,植食性种类有98种(65.33%),5189个体(86.35%)、肉食性种类有40种(26.67%),240个体(3.99%)、食菌性种类有10种(6.67%),578个体(9.62%)、食腐性种类有2种(1.33%),2个体(0.03%).冬麦田中栖息的甲虫种类及其物种丰富度和多度与1~4a不同年龄阶段的野花地有明显差异.这主要由于冬麦田中植物种类多样性低和植被结构简单而导致的.在不同演替阶段野花地中甲虫群落物种的丰富度一般在1~3a型野花地之间有差异.1年型野花地具有比较典型的甲虫群落结构,不同演替阶段的野花地对甲虫群落的定居,扩散及其演替过程中具有非常重要的作用.对甲虫提供丰富的食物资源和栖息,繁殖场所.因此,人为在农业区建立生态补偿区,有利于提高无脊椎动物和昆虫多样性,对物种保护方面具有重要意义. 展开更多

Harmonious regional development poses difficult problems, especially in so far as the harmonious regional development of ecological resources is concerned. China has explored several eco-compensation models, and in each province eco-compensation has different characteristics. These methods have had significant impacts. The aim of this paper is first to examine the meaning of ecocompensation and to present a framework for analyzing it. Next the development of eco-compensation in China is examined. Finally, four typical models of eco-compensation are compared: the government financial transfer payment compensation model; the ecological resource exploiters′ payment compensation model; the ecological destruction compensation model; and the ecological resource tax collection compensation model. Each model has its own unique feature and potential to contribute to harmonious regional development. 展开更多

At the end of the 1990 s China started to construct an ecological compensation system for national key ecological function areas. An eco-compensation system focusing on the "Transfer Payment of National Key Ecological Function Areas" has been established. The current eco-compensation system has played a positive role in improving the ecological environment of national key ecological function areas; but the ecological effect is weakening due to existing problems in the eco-compensation system such as unreasonable calculation of compensation standards, poor expression of rights and interests of stakeholders, simple sources of capital and modes of compensation. For better development, the eco-compensation system should be improved by(i) adhering to the combination of vertical compensation(oriented) and horizontal compensation(auxiliary) on the whole and establishing a transfer payment system of eco-compensation at national scale;(ii) defining the compensation standard according to ecological protection costs, development opportunity costs and ecological service values and adding indicators that reflect economic green transformation to evaluate compensation effects;(iii) gradually building a utilization system of eco-compensation funds in which multi-stakeholders participate and establishing a green development-oriented system to evaluate the performance of local governments; and(iv) cultivating a new business pattern where ecological services are the product, to grow the ecological service industry. 展开更多

Ecological compensation or eco-compensation has been implemented mainly through institutional arrangement in China. In the farming-pastoral transitional zone of Inner Mongolia, eco-compensation has been implemented in two modes, one for land use abandonment and the other for productionstructure adjustment. Based on a detailed field survey, this study performs a comparative analysis of the willingness of households to accept economic compensation and consequently evaluates the effects of the two eco-compensation modes. The mode of eco-compensation for land use abandonment lacks a mechanism for generating employment opportunities and so is unsustainable. In contrast, ecocompensation for production-structure adjustment makes the pastoral and farming scales of households decrease significantly and most importantly helps to generate more job opportunities. Although this mode faces households with more market risk, it provides an effective means for resolving conflicts between ecosystems restoration and regional socio-economic development. 展开更多

The land fallow policy was adopted by central and local governments to encourage the abandonment of water-intensive crops, such as winter wheat, in groundwater over-exploited areas. At the same time, since the 1990s, many households in the North China Plain (NCP) have chosen to replace the winter wheat and summer maize double-cropping system with the spring maize single-cropping system. Therefore, it is crucial to identify target land parcels for winter wheat abandonment and to design reasonable and proper standards for ecological compensation prior to the implementation of the land fallow policy in the NCP. In this study, multi-level Iogit models were used with household survey data in order to detect determinants across land parcel, household and village levels on household cropping system decisions; the opportunity costs for winter wheat abandonment were also calculated using cost-benefit analysis. The results show that: (1) land quality and irrigation condition at parcel level are two essential elements influencing household cropping system decisions. Nearly 70% of the total area of poor land and more than 90% of the total area of unirrigated land has suffered winter wheat abandonment. Target land parcels for the land fallow policy should be those that are irrigated and of high quality. (2) There were no significant differences between net profits from spring maize and summer maize under similar farming conditions, and the opportunity cost for winter wheat abandonment should be equal to the net profit of winter wheat. (3) The primary purpose of the land fallow policy is to induce groundwater recovery and restoration as a preliminary stage. A higher level of 350 yuan/mu is recommended as subsidy for ecological compensation at this stage. Later, the primary purpose of the policy should be a transition to a balance between exploitation and supplementation of water resources, and a lower level of 280 yuan/mu is recommended as a subsidy at this stage. 展开更多
