云南省岩溶地区石漠化草原现状及分区保护与修复策略

据最新调查数据,云南省石漠化草原主要分布于曲靖、昆明、红河等5个州( 市),总面积 37.97 万hm²,占岩溶土地面积的3.53%,其分布最广的海拔区间为1 500~2 500 m,占比47.85%, 基岩裸露度分布区间为30%~94%,以植被盖度为10%~19%的分布区间面积最广,占比37.85%, 绝大部分分布于土层薄甚至极薄区域,占比达92.10%。根据石漠化草原空间分布特征,在充分衔 接各大生态保护和修复工程建设规划基础上,统筹考虑岩溶生态系统的完整性、地理单元的连续性 和经济社会发展的可持续性,将云南省石漠化草原区划为6个分区,分区阐述石漠化草原生态保护 与修复策略。     

城乡共建田园综合体——城市近郊乡村用地规划研究

:在城市快速扩张的冲击下,城市乡村之间整体呈现出割裂关系,不利于社会的健康发展,城市边缘区乡村用地地位于城市农村的腹地,是未来城乡融合发展的桥梁纽带。随着乡村振兴战略的提出,以产业结构转型为代表的田园综合体为未来乡村发展提供了新的思路,本文探讨了在城乡融合背景下城市近郊乡村地区建设田园综合体的可行性、建设原则与建设思路。     

基于GIS的澳洲坚果在云南适宜种植区划分研究

为促进云南省澳洲坚果产业持续发展,利用GIS技术将7个气候要素和DEM网格图叠加分析,划分澳洲坚果在云南种植的最适宜、次适宜和不适宜区。结果表明,最适宜区面积57 939 km²,占云南省国土面积的14.7%;次适宜区面积63 977 km²,占云南省国土面积的16.2%。澳洲坚果可种植区域为文山州、红河州、普洱市、德宏州、临沧市、保山市、西双版纳州及玉溪南部地区,主要为云南热带、亚热带地区的河谷地带、低海拔山地区域。

西部农村发展奶牛小区的优势及注意问题

西部农村饲草资源充裕,发展奶牛养殖小区有利于减少草料运输费用,有利于减轻城郊养牛环境污染,有利于改善牛奶质量。本文提出小区建设应注意的五个问题:注重奶牛质量;采用胚胎移植技术,提高小区牛群的个体产奶量:种养结合,建立与奶牛养殖业配套的饲草生产基地;改进饲养管理,推行混合日粮饲养技术;实行行业准入制度,控制小区环境污染,提高牛奶质量,生产绿色奶品。     

重新认识农区山羊放牧饲养

文章从山羊养殖历史、生物学特性、自然社会、经济效益、生态环保、市场消费及国外养殖进展等方面进行研究,认为我国南方农区山羊饲养应回归放牧养羊,可以实现社会生态经济的可持续发展。同时提出放牧养殖的标准化建设思路。     

Comparative analysis of proteomic profiles between endometrial caruncular and intercaruncular areas in ewes during the peri-implantation period

The endometrium of sheep consists of plenty of raised intercaruncular areas （IC）. In order to better understand aglandular areas called caruncular （C）, and intensely glandular the endometrium involved mechanisms of implantation, we used LC-MS/MS technique to profile the proteome of ovine endometrial C areas and IC areas separately during the peri-implantation period, and then compared the proteomic profiles between these two areas. We successfully detected 1740 and 1813 proteins in C areas and IC areas respectively. By comparing the proteome of these two areas, we found 170 differentially expressed proteins （DEPs） （P 〈 0.05）, functional bioinformatics analysis showed these DEPs were mainly involved in growth and remodeling of endometrial tissue, cell adhesion and protein transport, and so on Our study, for the first time, provided a proteomic reference for elucidating the differences between C and IC areas, as an integrated function unit respectively, during the peri-implantation period. The results could help us to better understand the implantation in the ewes. In addition, we established a relatively detailed protein database of ovine endometrium, which provide a unique reference for further studies.     

鲁北滨海地区引种豆科牧草的灰色关联度分析

试验在鲁北滨海地区对经一般观察后初步入选的１４种豆科牧草进行了观察，并采用灰色关联度分析法以干草产量、鲜草产量、繁殖系数、折干率、叶量率、生长速度为主要指标进行综合评价。结果表明：综合性状最好的豆科牧草是草木樨属牧草，其中白花草木樨尤为突出；其次为沙打旺和美国苜蓿，也是适于鲁北滨海地区种植的豆科牧草。
