为了对退牧还草政策的实施效果进行客观的总结和评估,提供我国退牧还草政策实施和改进的科学依据,通过问卷和访谈等社会科学研究方法,对内蒙古、宁夏、青海、新疆和新疆生产建设兵团的331个牧户家庭进行了调查研究,并对退牧还草政策对牧民生产生活的影响和草原生态变化进行了分析研究。调查研究结果表明,退牧还草政策的实施有效地改善了草原生态环境,促进了牧民生产方式和生产结构的转变,改善了牧民的收入结构,使牧民生活水平有了一定提高。 相似文献

英国浪漫主义诗人华兹华斯崇尚自然,其诗歌不仅描绘和赞美了美丽的自然风光,而且还包含了他对自然与人类关系的哲学思考,充满了对自然的崇敬和热爱,表现了人与自然和谐共处、天人合一的生态意识。华兹华斯的生态意识继承了卢梭＂回归自然＂的思想,也启发了爱默生的超验主义思想。华兹华斯的浪漫主义诗歌唤起了人们对自然的热爱和对人生的思考,这正是华兹华斯诗歌的现实意义所在。 相似文献

A five-year-old, neutered male, Bernese Mountain Dog was referred because of a two-week history of hematuria and a one-week history of polydipsia and polyuria. Palpation of the dorsomedial mesogastrium revealed a mass on the left side, which was seen via radiography and ultrasonography to be attached to the left kidney. The left kidney and the attached mass were excised surgically, and the dog had an uneventful recovery. Histological examination of the mass revealed a dense proliferation of non-polymorphic spindle cells, which stained positive for smooth muscle actin via immunohistochemistry. Leiomyoma of the kidney was diagnosed. Postoperatively, there was mild azotaemia, which did not affect the general condition of the dog and was still present 15 months after surgery. Leiomyoma of the kidney is a benign tumor, and hematuria may be the only clinical sign. 相似文献

An 18‐year‐old stallion was presented for castration because of insidious, bilateral scrotal enlargement of one year's duration. The left testis was firm, while the right was soft and lobulated; both were larger than normal. Palpation of the scrotum and its contents did not cause the horse to show signs of discomfort. Ultrasonography of scrotal contents revealed abnormal, heterogeneous tissue with ill defined regions of hyper‐ and hypoechogenity throughout both testes. Several hours after admission the horse developed severe signs of colic. On the basis of anamnesis, clinical findings, and results of ultrasonography and transrectal palpation bilateral testicular neoplasia and incarcerated inguinal hernia were tentatively diagnosed. Because the horse's owner did not consent to surgical treatment, the stallion was subjected to euthanasia. Histological and immunohistochemical examination of the testicular tissue collected post mortem revealed a seminoma in the left testis and a leiomyoma in the right testis. The post mortem examination also revealed incarceration of the small intestine in addition to the testicular tumours. To our knowledge, this is the first report of the simultaneous presence of bilateral, yet different testicular tumour types in a stallion. 相似文献

A six-year-old, female Tibetan terrier was referred for investigation of a non-healing wound on the left caudal thorax. A subcutaneous swelling had initially developed on the chest wall, followed by a draining tract from which seropurulent fluid drained for two months. There had been no response to antibiotic treatment. Following radiographic and ultrasonographic examinations, a bone sequestrum from a fractured rib or a foreign body was suspected. Surgical exploration of the wound identified a sinus tract and a wooden foreign body (an ice-lolly stick) was located in subcutaneous tissues. Partial wound dehiscence of the surgical site occurred postoperatively, but healed after 10 days. One month later, fluid began to discharge from the area again. Further surgical exploration confirmed a gastrocutaneous fistula. Dissection of the fistula and surgical closure of the stomach, body wall and skin led to resolution of all signs. 相似文献
